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.

Compatibility
This kit's capacitors are universal replacements compatible with central air conditioners, heat pumps, and condensing units across all major HVAC brands, wherever the original capacitor's MFD rating matches one included in this kit and its voltage rating is 450V or lower (370V and 440V equipment included, since a higher voltage rating is always a safe upgrade).
Note: The MFD (microfarad) rating must match the original capacitor exactly on both the compressor and fan sides — do not substitute a different MFD value. If a job calls for a rating not included in this kit (such as a 25/5, 30/5, or 55/5), each individual dual run capacitor rating is also available separately in our HVAC capacitor line. Contact our support team if you'd like help confirming which rating a specific job needs.

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.

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.

Quick Answer
The XPARTCO XPDC40X5-450R 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. 40 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.

XPDC40X5-450R
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 40 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:
40 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
Universal dual run capacitor — supports both the compressor and condenser fan motor from one component
40 MFD compressor rating + 5 MFD fan motor rating in a single 3-terminal can
450VAC rating — a safe upgrade replacement for equipment originally speced at 370V or 440V
Round aluminum can construction
Resolves "hums but won't start," "fan spins slowly," "trips the breaker," and "bulging or leaking can" symptoms caused by capacitor failure

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 XPDC40X5-450R 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 40/5 MFD, 450VAC, round dual run capacitor rating — regardless of which HVAC brand originally installed it.

XPARTCO XPDC60X5-450R Dual Run Capacitor (60/5 MFD, 450V, Round)
The XPARTCO XPDC60X5-450R 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 60 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.

XPDC80X5-450R
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 80 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:
80 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 XPDC80X5-450R 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 80/5 MFD, 450VAC, round dual run capacitor rating — regardless of which HVAC brand originally installed it.

XPARTCO XPDC70X5-450R Dual Run Capacitor (70/5 MFD, 450V, Round)
The XPARTCO XPDC70X5-450R 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 70 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 XPDC70X5-450R 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. 70 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

XPARTCO W10350564 Refrigerator Run Capacitor Replaces WPW10350564
The XPARTCO W10350564 is an aftermarket replacement compressor run capacitor compatible with a wide range of Whirlpool, Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Roper, Admiral, Ikea, and Kenmore refrigerators and freezers. The run capacitor is a small but critical electrical component mounted near the compressor at the back of the refrigerator — it delivers a phase-shifted power boost that helps the compressor motor start at the beginning of each cooling cycle, and supports smooth, efficient motor operation while the compressor runs. When the capacitor fails — typically from dielectric breakdown, age, heat, or moisture intrusion — the compressor may fail to start, hum without starting, kick on and off repeatedly, or cause inconsistent cooling throughout the refrigerator.
Rated 12 µF (MFD) ±5% capacitance, 180VAC, 50/60Hz. This capacitor works together with the compressor start relay/start device — the two components are frequently replaced together, since a failed capacitor often stresses the relay and vice versa. It directly replaces WPW10350564, W10350564, AP6020176, PS11753490, EAP11753490, and 2683570. This is one of the most cost-effective refrigerator repairs — a failed run capacitor mimics symptoms of a failed compressor (a far more expensive repair), so testing and replacing the capacitor first can save hundreds of dollars. Installs in about 15 minutes with basic hand tools.
Quick Answer
The XPARTCO W10350564 Refrigerator Run Capacitor fixes Whirlpool, Maytag, KitchenAid, Jenn-Air, Amana, and Kenmore refrigerators and freezers where the compressor won't start, hums without starting, kicks on and off, or the fridge/freezer is too warm with inconsistent cooling. 12 µF (MFD) ±5%, 180VAC, 50/60Hz. Replaces WPW10350564, AP6020176, PS11753490, EAP11753490, 2683570. Often replaced together with the compressor start relay. A 15-minute repair that can save you from misdiagnosing a "failed compressor."
Common Problems This Part Fixes
Compressor won't start — no power boost from the failed capacitor
Compressor hums or clicks but doesn't start running
Compressor kicks on and off repeatedly (short cycling)
Refrigerator and freezer too warm — cooling cycles not completing
Fridge too warm while freezer seems okay — weak compressor operation
Noticeable humming sounds from the back of the refrigerator
Inconsistent cooling and variable temperatures inside the refrigerator
Refrigerator will not start at all
Capacitor visibly bulged, leaking, or burned
Capacitance test reads significantly off from 12 µF

Installation Notes
⚠️ Capacitor Safety Warning — Stored Electrical Charge Capacitors store an electrical charge even after the refrigerator is unplugged. Before handling the old capacitor, discharge it safely: with the refrigerator unplugged, touch the blade of an insulated-handle screwdriver across both capacitor terminals simultaneously to short them together (you may see or hear a small spark — that's the stored charge dissipating). Never touch the capacitor terminals with bare hands before discharging. If you're not comfortable with this step, have the repair done by a qualified appliance technician.
⚠️ Unplug Refrigerator Before Starting — Wear Work Gloves Unplug the refrigerator and pull it away from the wall to access the rear. Safely store any food that could spoil if the repair takes longer than expected. Wear work gloves to protect your hands. The run capacitor is located near the compressor at the bottom rear of the refrigerator, typically behind a lower rear access panel. Remove the screws holding the access panel and set it aside. Locate the capacitor — a small rectangular or oval component connected to the compressor's start relay/start device by wire terminals. Photograph the wire connections before disconnecting anything. Discharge the old capacitor before touching the terminals (see the safety warning above). Disconnect the wire terminals from the old capacitor — note which wire goes to which terminal. Release the capacitor from its mounting clip or bracket. Install the new W10350564 capacitor in the same position, secure the mounting clip, and reconnect the wires to the same terminals as photographed. While the panel is open, inspect the start relay/start device on the side of the compressor — if it rattles when shaken, shows burn marks, or has corroded terminals, replace it at the same time. Reinstall the rear access panel, push the refrigerator back into place, plug it in, and listen for the compressor to start smoothly within a few minutes. Allow several hours for the refrigerator to return to its set temperature. Tools needed: Phillips screwdriver, 1/4" nut driver, insulated-handle flathead screwdriver (for discharging), needle-nose pliers, work gloves.
Frequently Asked Questions
How do I know if the run capacitor has failed and not the compressor?
This is the key question — because a failed $15–30 capacitor produces nearly identical symptoms to a failed $300+ compressor. Signs pointing to the capacitor: the compressor hums or clicks but won't start; the compressor tries to start, runs briefly, then shuts off (short cycling); or the refrigerator gradually stopped cooling with humming from the rear. To test: unplug the refrigerator, discharge the capacitor, disconnect it, and measure it with a multimeter that has a capacitance setting — a healthy capacitor reads close to 12 µF (within ±5%). A reading far off, zero, or infinite confirms the capacitor has failed. Visual signs like bulging, leaking, or burn marks also confirm failure. Given the low cost, replacing the capacitor (and start relay) first is the standard diagnostic approach before condemning the compressor.
Should I replace the start relay at the same time?
Yes, it's strongly recommended. The run capacitor and the compressor start relay/start device work together in the compressor's starting circuit — the relay switches power to the start winding while the capacitor provides the phase-shifted boost. When one fails, the other has typically been stressed by the same electrical events (voltage spikes, overheating, repeated failed start attempts). Both components are inexpensive, mounted in the same location on or near the compressor, and accessible in the same repair session. A quick relay check: with the refrigerator unplugged, remove the relay and shake it — if it rattles, the internal components have failed and it needs replacement.
Why does the capacitor need to be discharged before handling?
Capacitors store electrical energy — that's their job. Even after the refrigerator is unplugged, the capacitor can hold a charge capable of delivering a painful (and potentially dangerous) shock when you touch both terminals. Before handling, always discharge the capacitor by shorting both terminals together with the blade of an insulated-handle screwdriver — touch the metal blade across both terminals at once and hold for a second or two. You may see a small spark as the charge dissipates; that's normal. After discharging, the capacitor is safe to handle. This takes five seconds and eliminates the shock risk entirely.
What's the difference between a run capacitor and a start capacitor?
Both assist the compressor motor but in different phases of operation. A start capacitor delivers a large, brief boost only during the initial moment of motor startup, then is switched out of the circuit. A run capacitor — like the W10350564 — stays in the circuit continuously while the motor runs, providing an ongoing phase shift that improves the motor's running efficiency and torque. Household refrigerators on the Whirlpool platform typically use a run capacitor working alongside the start relay/start device. Match the replacement to your original: the W10350564 is a 12 µF, 180VAC run capacitor, and the capacitance rating must match for correct compressor operation.
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 (12 µF ±5%, 180VAC, 50/60Hz), terminal configuration, and compressor-support function of the original WPW10350564/W10350564 run capacitor used in compatible Whirlpool, Maytag, KitchenAid, Jenn-Air, Amana, and Kenmore refrigerators and freezers.
