XPARTCO 297259515 Refrigerator Start Relay & 297286803 Capacitor
The XPARTCO 297259515 kit bundles the compressor start relay and the matching run capacitor for Frigidaire, Kenmore, Crosley, Kelvinator, Gibson, Tappan, and Westinghouse refrigerators and freezers. These two components mount together at the compressor and work as a team every time the compressor cycles on: the start relay delivers the initial electrical boost needed to get the compressor's start winding moving, and the run capacitor helps the compressor motor start and run efficiently once it's going. Because they sit side by side on the same compressor terminals and tend to be diagnosed together, replacing both at once is the standard, most reliable fix rather than gambling on which single component has failed.
The classic failure symptom for this pair is unmistakable: a repeated clicking sound from the compressor area as the relay tries and fails to start the compressor, paired with a refrigerator and freezer that are both running too warm because the compressor never actually starts. Real-world repair accounts back this up — technicians troubleshooting a clicking-but-not-starting compressor commonly find both the start relay and run capacitor bad at the same time, which is exactly why they're sold together as a kit. It directly replaces, for the relay: 297259502, 297259510, PS11728176, 4378266, AP5986809, EAP11728176; and for the capacitor: AP5306470, 216985001, 297286804, 1465079, 1940424, 215329902, 218909915, 7216985001, 7218909915, AH3495561, EA3495561, PS3495561, and EAP3495561.
Quick Answer
The XPARTCO 297259515 Refrigerator Start Relay & Capacitor Kit fixes Frigidaire, Kenmore, Crosley, Kelvinator, Gibson, Tappan, and Westinghouse refrigerators and freezers that won't start cooling, run too warm in both compartments, or make a repeated clicking sound from the compressor area. Includes start relay (297259515) and run capacitor (297286803). Capacitors store a dangerous electrical charge even after power is disconnected — always discharge before handling.

Note on capacitor voltage: Manufacturer-facing sources disagree on this capacitor's voltage rating — some list it as 15µF/120V, others as 15µF/250V. Before installing, check the voltage printed directly on your original capacitor's body and confirm the new capacitor's printed rating matches or exceeds it. We're not publishing a single voltage figure here rather than risk stating the wrong one — contact our support team if you'd like help confirming the correct rating for your model.
Installation Notes
⚠️ Danger — The Run Capacitor Stores A Dangerous Electrical Charge Shut off power to the refrigerator at the outlet before beginning. The run capacitor stores an electrical charge even after power has been disconnected, and that charge can deliver a serious shock. Before touching the capacitor's terminals, discharge it by shorting the two terminals together using an insulated-handle screwdriver, or a proper capacitor discharge tool with a resistor. Never short the terminals with a bare metal tool held with your bare hand.
⚠️ Unplug Refrigerator Before Starting — Both Components Mount To The Compressor Disconnect power at the outlet before beginning, and move perishable food to a cooler for the duration of the repair. Shut off the water supply as well if your model has an ice maker or water dispenser. Wear work gloves and safety glasses. Have an assistant help pull the refrigerator away from the wall for access to the rear panel. Locate the compressor in the machine compartment at the back or bottom of the unit, and find the start relay and run capacitor mounted directly to its terminals. Photograph the wiring and orientation of both components before removing anything. After confirming the capacitor is fully discharged, disconnect the old relay and capacitor from the compressor terminals, noting each terminal position. Install the new 297259515 relay and 297286803 capacitor from this kit in the same orientation, seating each firmly onto the correct compressor terminals. Reassemble any panels or retainers you removed, restore the water supply if applicable, and push the refrigerator back into place. Restore power and monitor the refrigerator over the next few hours to confirm the compressor starts reliably and both compartments begin cooling. Tools needed: 1/4" nut driver or socket, 1/2" wrench or adjustable wrench, needle nose pliers, flat-head screwdriver, insulated-handle screwdriver or capacitor discharge tool, work gloves, safety glasses.
Frequently Asked Questions
Do I really need both the relay and the capacitor, or could just one be bad?
Either could technically be the sole cause, but in practice, technicians troubleshooting a compressor that clicks but won't start commonly find both the start relay and run capacitor have failed together — they sit on the same terminals under the same electrical stress every time the compressor cycles. Replacing both at once avoids having to open the compressor compartment a second time if the remaining original part fails shortly after.
I hear a repeated clicking sound from the back of my refrigerator, but it's not cooling. Is this the kit I need?
Yes, this is a textbook symptom for this exact pair of components. The clicking is the sound of the relay repeatedly attempting to engage the compressor's start winding and failing, often because the run capacitor isn't providing the boost the compressor needs to actually get moving. If both compartments are also warm, that confirms the compressor isn't starting at all.
Why doesn't this listing state a single voltage rating for the capacitor?
We found genuinely conflicting information across manufacturer-facing sources for this specific capacitor — some list it at 120V, others at 250V — and we'd rather flag that honestly than publish a number we can't fully verify. Before installing, check the rating printed directly on your original capacitor's body, and contact our support team if you'd like help confirming the correct value for your model.
My refrigerator stopped suddenly during normal operation. Could this kit be the cause?
Yes, a failing run capacitor or start relay can cause a refrigerator to stop suddenly, not just fail to start from cold. If your unit was running fine and then abruptly stopped cooling, checking these two components at the compressor is a reasonable next step alongside checking for tripped breakers or other obvious causes.
Is this an OEM or aftermarket kit?
This is an aftermarket replacement kit built to OEM-equivalent quality standards. It is not a genuine Frigidaire OEM kit, but each component is manufactured to match the electrical specifications and terminal fit of the original 297259515 start relay and 297286803 run capacitor used in compatible Frigidaire, Kenmore, Crosley, Kelvinator, Gibson, Tappan, and Westinghouse refrigerators and freezers.

XPARTCO HVAC Capacitor Contractor Pack — 18-Piece Assortment Kit (Dual + Single Run)
The XPARTCO HVAC Capacitor Contractor Pack bundles the seven most commonly needed dual run capacitor ratings, plus two single run capacitor ratings, into a single 18-piece kit, so a technician can carry one box instead of restocking capacitors between jobs. Each dual run capacitor combines two capacitors into one round, three-terminal can — one rated for the compressor, one for the condenser fan motor — the standard design used across the vast majority of residential and light commercial split systems, window units, and heat pumps. The single run capacitors are 2-terminal units sized for one motor circuit, commonly used on standalone condenser fan motors, pool pumps, and other single-phase motor equipment.
The mix in this kit is weighted toward the ratings that fail most often in the field: 35/5, 40/5, and 45/5 MFD capacitors cover the majority of residential 1.5–3.5 ton systems and are included in higher quantities, while 50/5, 60/5, 70/5, and 80/5 MFD round out coverage for larger residential and light commercial compressors. All fourteen capacitors are rated 450VAC, so each one is a safe upgrade replacement regardless of whether the original equipment was speced at 370V, 440V, or 450V.
Quick Answer
The XPARTCO HVAC Capacitor Contractor Pack is an 18-piece assortment covering the seven dual run capacitor ratings most commonly replaced on residential and light commercial AC systems and heat pumps, plus two single run capacitor ratings for fan motors and similar equipment: 35/5 (×2), 40/5 (×4), 45/5 (×4), 50/5 (×1), 60/5 (×1), 70/5 (×1), 80/5 (×1), single-run 5 (×2), and single-run 7.5 (×2) MFD, all rated 450VAC, round. Built for technicians who want to stock a truck once instead of reordering capacitors mid-week. Capacitors store a dangerous electrical charge even after power is disconnected — always discharge before handling.

Installation Notes
⚠️ Danger — Capacitors Store A Dangerous Electrical Charge Shut off power to the outdoor unit at the disconnect box and at the breaker before beginning any capacitor replacement. A capacitor stores an electrical charge even after power has been disconnected, and that charge can deliver a serious or fatal shock. Before touching any terminal, discharge the capacitor fully: on a dual run capacitor, short each pair of terminals together (C-to-Fan, C-to-Herm, and Fan-to-Herm); on a single run capacitor, short the two terminals together. Use an insulated-handle screwdriver, or a proper capacitor discharge tool with a resistor. Never short the terminals with a bare metal tool held with your bare hand.
⚠️ Match The Rating Before Installing — Photograph Wiring First Confirm the failed capacitor's MFD rating on both the compressor and fan sides, and select the matching piece from this kit — the rating printed on the old capacitor's can is the reference, not the equipment's tonnage. Photograph the wiring on the old capacitor's terminals before disconnecting anything; terminals are typically labeled C (Common), Herm or Comp (compressor), and Fan. Remove the mounting strap holding the old capacitor, disconnect each wire, and install the replacement from this kit in the same mounting position, reconnecting each wire to the matching terminal. Restore power and confirm the compressor and fan both start promptly and run smoothly. Tools needed: insulated-handle screwdriver or capacitor discharge tool, nut driver, work gloves, safety glasses.
Frequently Asked Questions
Why are 35/5, 40/5, and 45/5 included in higher quantities than the others?
These three ratings cover the size range used on the largest share of residential split systems in the field, so they're the ratings most likely to come up repeatedly across a week of service calls. The larger ratings (50/5 through 80/5) still come up regularly but less often, which is why the kit includes one of each rather than duplicates.
What if a job needs a rating that isn't in this kit, like 25/5 or 55/5?
Every rating in this kit — both dual run and single run — is also sold individually, so you can pick up less common values as needed without buying another full kit. Contact our support team if you want help identifying which individual rating a specific job calls for.
Can I use a 450V capacitor from this kit to replace an original 370V or 440V capacitor?
Yes. Voltage rating is a ceiling, not an exact match requirement — a capacitor rated for a higher voltage than the original works safely and often lasts longer under the same electrical stress. What you can't do is go the other direction, so every capacitor in this kit being 450V means it's a safe fit anywhere the original was rated 370V, 440V, or 450V.
Does the MFD rating need to match exactly, or is there some tolerance?
Match the rating on both the compressor and fan side as closely as possible to the original — these capacitors carry a ±5% manufacturing tolerance, but that's not the same as intentionally substituting a different rated value. Always select the kit piece whose printed MFD rating matches what was on the failed capacitor.
Is this a genuine OEM kit?
This is a universal replacement kit rather than a brand-specific OEM product. Because dual run capacitors are a standardized component defined by their electrical specifications rather than their manufacturer, each capacitor in this kit is a correct replacement for any unit's original capacitor sharing the same rating — regardless of which HVAC brand originally installed it.

XPARTCO XPDC45X5-450R Dual Run Capacitor (45/5 MFD, 450V, Round)
The XPARTCO XPDC45X5-450R is a universal dual run capacitor for central air conditioners, heat pumps, and condensing units. A run capacitor works alongside a single-phase AC motor to keep it running efficiently once it's started, boosting torque and correcting the phase of the current feeding the motor's windings. This is a dual capacitor, meaning it combines two separate capacitors — one for the compressor, one for the condenser fan motor — into a single three-terminal can, which is why nearly every residential outdoor AC unit uses exactly this style of component to run both motors from one part.
Rated 45 MFD for the compressor circuit and 5 MFD for the fan motor circuit, at 450VAC, in a round aluminum can housing. Because a capacitor's voltage rating is a ceiling rather than a fixed match, this 450V-rated capacitor can safely replace an original capacitor rated 370V or 440V — going higher on voltage is always safe, going lower is not. Over time, the dielectric material inside a run capacitor breaks down from heat cycling and electrical stress, causing it to lose capacitance or fail outright. A failing dual capacitor produces a very recognizable set of symptoms: the outdoor unit hums but the compressor or fan won't start, the fan spins slowly or needs a manual push to get going, the system trips the breaker, or the capacitor can itself is visibly bulging, domed, or leaking oily residue at the top.
Quick Answer
The XPARTCO XPDC45X5-450R Dual Run Capacitor fixes central air conditioners and heat pumps where the outdoor unit hums but won't start, the compressor or fan motor won't run, the fan spins slowly or needs a manual push, the breaker trips, or the capacitor can is visibly bulged or leaking. 45 MFD (compressor) + 5 MFD (fan) dual capacitor, 450VAC, round, 3-terminal. Universal fit for equipment originally speced at 370V or 440V, since a higher voltage rating is always a safe upgrade. Capacitors store a dangerous electrical charge even after power is disconnected — always discharge before handling.

XPDC45X5-450R
This is a universal component rather than a single-manufacturer part, so the specific OEM number your HVAC system's label references will vary by brand (Goodman, Trane, Carrier, Rheem, York, Lennox, Amana, and others). This capacitor is a correct replacement for any dual run capacitor matching the 45 MFD / 5 MFD rating with a voltage rating of 450V or lower. If you have your original part number, contact our support team and we will verify compatibility before you order.
Compatibility
This dual run capacitor is a universal replacement compatible with central air conditioners, heat pumps, and condensing units across all major HVAC brands, wherever the original capacitor is rated:
45 MFD (compressor) + 5 MFD (fan motor)
370V, 440V, or 450V (this capacitor's 450V rating exceeds and safely replaces either lower rating)
Round can shape with 3 terminals
Note: The MFD (microfarad) rating must match your original capacitor exactly on both sides — do not substitute a different MFD value for either the compressor or fan side. Voltage rating, on the other hand, can be equal to or higher than the original (450V safely replaces 370V or 440V), but never lower. Can shape (round vs. oval) affects only physical fit inside your unit's electrical compartment, not performance. If you're unsure of your original capacitor's specifications, they're printed directly on its can — contact our support team if you'd like help confirming compatibility.
Key Features

Installation Notes
⚠️ Danger — Capacitors Store A Dangerous Electrical Charge Shut off power to the outdoor unit at the disconnect box and at the breaker before beginning. A capacitor stores an electrical charge even after power has been disconnected, and that charge can deliver a serious or fatal shock. Before touching any terminal, discharge the capacitor by shorting each pair of terminals together (C-to-Fan, C-to-Herm, and Fan-to-Herm) using an insulated-handle screwdriver, or by using a proper capacitor discharge tool with a resistor. Never short the terminals with a bare metal tool held with your bare hand. If you are not fully comfortable performing a capacitor discharge safely, have a qualified HVAC technician replace this part instead.
⚠️ Photograph The Wiring Before Disconnecting — Match Terminals Exactly Wear work gloves and safety glasses. After confirming the capacitor is fully discharged, photograph the wiring on the old capacitor's terminals before disconnecting anything — dual capacitors are labeled C (Common), Herm or Comp (compressor/hermetic), and Fan, and getting a wire on the wrong terminal can damage the new capacitor or the motor it feeds. Note which terminal each wire came from, or label them individually with tape. Remove the mounting strap or bracket holding the old capacitor in its housing, and disconnect each wire from its terminal. Install the new XPDC45X5-450R in the same mounting position, secure it with the strap or bracket, and reconnect each wire to the matching terminal (C, Herm, and Fan) exactly as labeled. Double-check every connection before restoring power. Restore power at the breaker and disconnect box, and confirm the compressor and fan both start promptly and run smoothly. Tools needed: insulated-handle screwdriver or capacitor discharge tool, nut driver, work gloves, safety glasses.
Frequently Asked Questions
My AC unit hums but won't start. Is this the capacitor?
It's one of the most common causes of exactly that symptom. A run capacitor gives the compressor or fan motor the extra push needed to start turning; without it, the motor can draw power and hum in place without ever actually starting to spin. If you can see the capacitor can and it looks bulged, domed on top, or is leaking a brown oily residue, that's strong visual confirmation of failure.
Can I use a 450V capacitor to replace my old 370V or 440V one?
Yes. Voltage rating is a ceiling, not an exact match requirement — a capacitor rated for a higher voltage than your original will work safely and often lasts longer under the same electrical stress. What you cannot do is go the other direction: never install a capacitor with a lower voltage rating than your original, since that risks premature failure or the capacitor breaking down under normal operating conditions.
Does the round vs. oval shape matter?
Only for physical fit inside your unit's electrical compartment — it has no effect on electrical performance. If your unit's mounting bracket or available space is sized for a round can, use a round capacitor; if it's sized for an oval can, use an oval one. The MFD and voltage ratings are what matter electrically, not the shape.
The fan spins if I give it a push, but won't start on its own. What does that mean?
This is a classic sign of a weak or failing capacitor — it may still have enough charge to keep the motor running once it's already spinning, but not enough to provide the initial starting torque. This is a strong signal to replace the capacitor before it fails completely and leaves you with no cooling at all.
Is this a genuine OEM part?
This is a universal replacement part rather than a brand-specific OEM part. Because dual run capacitors are a standardized component defined by their electrical specifications rather than their manufacturer, this capacitor is a correct replacement for any unit's original capacitor that shares the same 45/5 MFD, 450VAC, round dual run capacitor rating — regardless of which HVAC brand originally installed it.

XPARTCO W10613606 Refrigerator Compressor Start Relay and Capacitor
The XPARTCO W10613606 is an aftermarket replacement compressor start relay and capacitor assembly compatible with a wide range of Whirlpool, Kenmore, Maytag, KitchenAid, Amana, Jenn-Air, Admiral, Crosley, Dacor, Hardwick, Inglis, Litton, and Magic Chef refrigerators. The start relay is a small but critical electrical component that plugs directly onto the compressor terminals and provides the initial power surge needed to start the compressor motor. Once the compressor reaches operating speed, the relay drops out — leaving the compressor to run on its own. The capacitor (rated 15µF ±5%, 250VAC) works alongside the relay to store and release the burst of electrical energy needed on startup.
When the start relay fails, the compressor cannot start — causing the refrigerator to stop cooling entirely. A failed relay typically produces a clicking sound every few minutes as the compressor tries and fails to start, followed by a short rest, then another attempt. This kit includes both the start relay and the CBB61 capacitor. It directly replaces W10416065, 8208290, 8208368, C8931605, 67003186, 67005560, 67005561, 67005562, 67003764, 8171210, and several additional cross-reference numbers. Installs in under 15 minutes — no tools required in most cases.

Installation Notes
⚠️ Unplug Refrigerator Before Starting Unplug the refrigerator from the power outlet before beginning. Move the refrigerator away from the wall to access the rear or lower back panel. Remove the rear access panel by unscrewing the retaining screws to expose the compressor. The compressor is a large black dome-shaped component — the start relay and capacitor assembly plugs onto the side terminals. Grip the old relay firmly and pull it straight off the compressor pins. Shake it — if it rattles, the internal contacts have failed and replacement is confirmed. Compare the old relay to the new W10613606 to confirm the terminal layout matches. Align the new relay with the compressor pins and press it firmly on. Reinstall the access panel, restore power, and listen for the compressor to start and run normally within a few minutes. Note: Some models may require trimming the wire connector tabs or reversing the connector orientation for a proper fit — do not force the connection. Tools needed: Phillips screwdriver (for panel access only).
Frequently Asked Questions
What does the compressor start relay do?
The start relay plugs onto the compressor terminals and provides the brief but powerful surge of electrical current needed to start the compressor motor from a standstill. Once the compressor reaches operating speed — usually within a second or two — the relay drops out and the compressor runs on its own. Without a working start relay, the compressor cannot start at all, and the refrigerator stops cooling. The capacitor works alongside the relay to store and deliver the extra energy needed on startup.
How do I know if my start relay has failed?
The most reliable quick test is the rattle test: unplug the refrigerator, pull the start relay off the compressor, and shake it near your ear. A working relay is silent. A failed relay will rattle — the internal contacts have broken free and are loose inside the casing. Another sign is a repeated clicking sound every 2–5 minutes from the back of the refrigerator, where the compressor attempts to start, fails, trips the overload protector, rests, and tries again. If the fridge is warm and you hear clicking, check the relay first.
What is the difference between the start relay and the capacitor?
The start relay is the switching device that connects and disconnects the start winding of the compressor motor during startup. The capacitor stores a charge and releases it during startup to give the motor the additional torque it needs to get moving under load. Together they work as a startup system for the compressor. This kit includes both — replacing both at the same time ensures the complete startup circuit is fresh and reliable.
My fridge is still not cooling after replacing the start relay — what else could it be?
If replacing the start relay does not restore cooling, other possible causes include a failed compressor (the compressor runs but no longer builds pressure), a refrigerant leak in the sealed system, a failed start capacitor (if not replaced along with the relay), a bad overload protector, or a faulty main control board. Listen carefully after installing the new relay — if the compressor now starts and runs but the fridge still doesn't cool after several hours, a sealed system issue or refrigerant problem is likely and will require a certified technician.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured to match the electrical specifications and terminal configuration of the original W10613606 start relay and capacitor assembly.

XPARTCO XPDC35X5-450R Dual Run Capacitor (35/5 MFD, 450V, Round)
The XPARTCO XPDC35X5-450R is a universal dual run capacitor for central air conditioners, heat pumps, and condensing units. A run capacitor works alongside a single-phase AC motor to keep it running efficiently once it's started, boosting torque and correcting the phase of the current feeding the motor's windings. This is a dual capacitor, meaning it combines two separate capacitors — one for the compressor, one for the condenser fan motor — into a single three-terminal can, which is why nearly every residential outdoor AC unit uses exactly this style of component to run both motors from one part.
Rated 35 MFD for the compressor circuit and 5 MFD for the fan motor circuit, at 450VAC, in a round aluminum can housing. Because a capacitor's voltage rating is a ceiling rather than a fixed match, this 450V-rated capacitor can safely replace an original capacitor rated 370V or 440V — going higher on voltage is always safe, going lower is not. Over time, the dielectric material inside a run capacitor breaks down from heat cycling and electrical stress, causing it to lose capacitance or fail outright. A failing dual capacitor produces a very recognizable set of symptoms: the outdoor unit hums but the compressor or fan won't start, the fan spins slowly or needs a manual push to get going, the system trips the breaker, or the capacitor can itself is visibly bulging, domed, or leaking oily residue at the top.
Quick Answer
The XPARTCO XPDC35X5-450R Dual Run Capacitor fixes central air conditioners and heat pumps where the outdoor unit hums but won't start, the compressor or fan motor won't run, the fan spins slowly or needs a manual push, the breaker trips, or the capacitor can is visibly bulged or leaking. 35 MFD (compressor) + 5 MFD (fan) dual capacitor, 450VAC, round, 3-terminal. Universal fit for equipment originally speced at 370V or 440V, since a higher voltage rating is always a safe upgrade. Capacitors store a dangerous electrical charge even after power is disconnected — always discharge before handling.
Common Problems This Part Fixes
Outdoor AC unit hums but the compressor won't start
Condenser fan won't spin, or spins slowly and needs a manual push to get going
System trips the breaker shortly after starting
AC blows warm air because the compressor isn't running
Repeated clicking sound from the contactor as it tries and fails to start the motor
Capacitor can visibly bulging, domed on top, or leaking oily residue
System that used to start slowly and has now stopped starting altogether
Burning smell from the outdoor unit's electrical compartment

XPDC35X5-450R
This is a universal component rather than a single-manufacturer part, so the specific OEM number your HVAC system's label references will vary by brand (Goodman, Trane, Carrier, Rheem, York, Lennox, Amana, and others). This capacitor is a correct replacement for any dual run capacitor matching the 35 MFD / 5 MFD rating with a voltage rating of 450V or lower. If you have your original part number, contact our support team and we will verify compatibility before you order.
Compatibility
This dual run capacitor is a universal replacement compatible with central air conditioners, heat pumps, and condensing units across all major HVAC brands, wherever the original capacitor is rated:
35 MFD (compressor) + 5 MFD (fan motor)
370V, 440V, or 450V (this capacitor's 450V rating exceeds and safely replaces either lower rating)
Round can shape with 3 terminals
Note: The MFD (microfarad) rating must match your original capacitor exactly on both sides — do not substitute a different MFD value for either the compressor or fan side. Voltage rating, on the other hand, can be equal to or higher than the original (450V safely replaces 370V or 440V), but never lower. Can shape (round vs. oval) affects only physical fit inside your unit's electrical compartment, not performance. If you're unsure of your original capacitor's specifications, they're printed directly on its can — contact our support team if you'd like help confirming compatibility.

Installation Notes
⚠️ Danger — Capacitors Store A Dangerous Electrical Charge Shut off power to the outdoor unit at the disconnect box and at the breaker before beginning. A capacitor stores an electrical charge even after power has been disconnected, and that charge can deliver a serious or fatal shock. Before touching any terminal, discharge the capacitor by shorting each pair of terminals together (C-to-Fan, C-to-Herm, and Fan-to-Herm) using an insulated-handle screwdriver, or by using a proper capacitor discharge tool with a resistor. Never short the terminals with a bare metal tool held with your bare hand. If you are not fully comfortable performing a capacitor discharge safely, have a qualified HVAC technician replace this part instead.
⚠️ Photograph The Wiring Before Disconnecting — Match Terminals Exactly Wear work gloves and safety glasses. After confirming the capacitor is fully discharged, photograph the wiring on the old capacitor's terminals before disconnecting anything — dual capacitors are labeled C (Common), Herm or Comp (compressor/hermetic), and Fan, and getting a wire on the wrong terminal can damage the new capacitor or the motor it feeds. Note which terminal each wire came from, or label them individually with tape. Remove the mounting strap or bracket holding the old capacitor in its housing, and disconnect each wire from its terminal. Install the new XPDC35X5-450R in the same mounting position, secure it with the strap or bracket, and reconnect each wire to the matching terminal (C, Herm, and Fan) exactly as labeled. Double-check every connection before restoring power. Restore power at the breaker and disconnect box, and confirm the compressor and fan both start promptly and run smoothly. Tools needed: insulated-handle screwdriver or capacitor discharge tool, nut driver, work gloves, safety glasses.
Frequently Asked Questions
My AC unit hums but won't start. Is this the capacitor?
It's one of the most common causes of exactly that symptom. A run capacitor gives the compressor or fan motor the extra push needed to start turning; without it, the motor can draw power and hum in place without ever actually starting to spin. If you can see the capacitor can and it looks bulged, domed on top, or is leaking a brown oily residue, that's strong visual confirmation of failure.
Can I use a 450V capacitor to replace my old 370V or 440V one?
Yes. Voltage rating is a ceiling, not an exact match requirement — a capacitor rated for a higher voltage than your original will work safely and often lasts longer under the same electrical stress. What you cannot do is go the other direction: never install a capacitor with a lower voltage rating than your original, since that risks premature failure or the capacitor breaking down under normal operating conditions.
Does the round vs. oval shape matter?
Only for physical fit inside your unit's electrical compartment — it has no effect on electrical performance. If your unit's mounting bracket or available space is sized for a round can, use a round capacitor; if it's sized for an oval can, use an oval one. The MFD and voltage ratings are what matter electrically, not the shape.
The fan spins if I give it a push, but won't start on its own. What does that mean?
This is a classic sign of a weak or failing capacitor — it may still have enough charge to keep the motor running once it's already spinning, but not enough to provide the initial starting torque. This is a strong signal to replace the capacitor before it fails completely and leaves you with no cooling at all.
Is this a genuine OEM part?
This is a universal replacement part rather than a brand-specific OEM part. Because dual run capacitors are a standardized component defined by their electrical specifications rather than their manufacturer, this capacitor is a correct replacement for any unit's original capacitor that shares the same 35/5 MFD, 450VAC, round dual run capacitor rating — regardless of which HVAC brand originally installed it.

XPARTCO HS810 Refrigerator 3-in-1 Hard Start Kit 1/12 to 1/5 HP 120V
The XPARTCO XPHS810 is a universal 3-in-1 hard start kit that combines a solid-state starting relay, a start capacitor, and thermal overload protection into a single prewired unit for refrigerator and freezer compressors rated 1/12 to 1/5 HP at 120V (110–125VAC). It's designed as a direct equivalent to the widely used Supco RCO810 and similar kits, giving a struggling compressor extra starting torque to overcome internal friction and gas pressure at startup — commonly used to fix the classic "click-buzz-click" no-start symptom without replacing the entire compressor.
The kit is fully prewired with color-coded leads (typically black = Common, white = Start, red = Run) and mounts directly onto the compressor's terminal pins, with instructions printed on the unit itself. It directly replaces Supco RCO810, URCO810, URC0810, RC0810, RC100, TJ90RCO810, AP4503019, ERP810, ERPU810, HS8, HS810, HS81, PCS810, and Mars 32781. Installs in 15–30 minutes with basic hand tools.
Quick Answer
The XPARTCO HS810 3-in-1 Hard Start Kit fixes refrigerators and freezers whose compressor makes a repeated "click-buzz-click" sound and fails to start, or that shut off on thermal overload during startup. Combines relay, start capacitor, and overload protector in one prewired unit for 1/12 to 1/5 HP compressors, 120V, 3.5A RLA. Replaces Supco RCO810, URCO810, RC0810, RC100, TJ90RCO810, AP4503019, ERP810, HS8, HS810, HS81, PCS810, Mars 32781. Do not install on LG linear/inverter compressors — see Installation Notes.
Common Problems This Part Fixes
Compressor makes a repeated "click-buzz-click" noise and fails to start
Refrigerator or freezer runs warm because the compressor won't stay running
Compressor hums but doesn't start, then trips off on overload
Refrigerator cycles on and off rapidly without reaching temperature
Older or worn compressor that starts hard, especially after a power outage
⚠ Capacitor Hazard — Read Before Servicing This kit contains a start capacitor, which can store a dangerous electrical charge even after the refrigerator is unplugged. Always disconnect power before servicing, and discharge the capacitor safely (using an insulated-handle resistor tool or by briefly shorting the terminals with an insulated screwdriver) before handling it. Never touch capacitor terminals with bare hands. If you are not comfortable working around stored electrical charge, have this repair performed by a qualified technician.

Installation Notes
⚠️ Unplug Refrigerator Before Starting — Discharge Capacitor Safely Disconnect power before beginning. Before touching any wiring, check your compressor's data label to confirm it is NOT a linear/inverter/BLDC compressor — this kit is not compatible with those and can damage the inverter board if connected. Access the compressor compartment, typically at the rear or bottom of the unit. Remove the existing relay/overload assembly by gently pulling it straight off the compressor terminal pins — do not force or twist. Use a multimeter to confirm which pins are Common (C), Start (S), and Run (R) if not already labeled. Connect the hard start kit's wires to the matching pins. Wire the kit's main power leads into the refrigerator's supply wiring using wire nuts, following the included diagram. Secure the kit with zip ties or its mounting strap to prevent vibration damage during compressor operation. Restore power and confirm the compressor starts smoothly without repeated clicking. Tools needed: nut driver or screwdriver, digital multimeter, wire nuts, insulated screwdriver (for capacitor discharge).
Frequently Asked Questions
My compressor makes a clicking or buzzing sound and won't start — will this fix it?
A hard start kit resolves this in many cases, especially on older or worn compressors that struggle to overcome internal gas pressure at startup. However, "click-buzz-click" can also indicate a failing compressor winding or a compressor nearing end of life. If the hard start kit doesn't resolve the issue, the compressor itself may need replacement — a hard start kit can extend a marginal compressor's life but can't revive one with failed internal windings.
Can I use this on any refrigerator?
This kit works on standard PSC and RSIR compressors within the 1/12 to 1/5 HP range at 120V. It is NOT compatible with LG linear/inverter compressors or any variable-speed inverter-driven compressor — connecting it to one of those can destroy the inverter control board. Check your compressor's label for "Inverter," "Linear," "BLDC," or "Digital" before ordering.
Do I need to remove my existing start capacitor or relay first?
Yes — remove the old relay/overload assembly from the compressor terminal pins before installing this kit. The XPHS810 is designed to work with or without an existing separate run capacitor remaining in the circuit, but the old start relay and any old start capacitor should be removed and replaced by this kit, not left in place alongside it.
Is this safe to install myself?
Many DIYers install hard start kits successfully, but this repair involves a capacitor that can hold a dangerous electrical charge even after the unit is unplugged, plus correctly identifying compressor terminals. If you're not comfortable working around stored electrical charge or don't have a multimeter to confirm terminal identification, we'd recommend having a qualified technician perform this repair.
