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. What's In The Kit Capacitor Rating Qty Typical Application 35/5 MFD, 450V, Round 2 Smaller residential split systems, window/PTAC units 40/5 MFD, 450V, Round 4 Common residential 2–2.5 ton systems — high-frequency replacement size 45/5 MFD, 450V, Round 4 Common residential 2.5–3 ton systems — high-frequency replacement size 50/5 MFD, 450V, Round 1 Mid-size residential systems, 3–3.5 ton 60/5 MFD, 450V, Round 1 Larger residential systems, 3.5–4 ton 70/5 MFD, 450V, Round 1 Larger residential/light commercial systems, 4–5 ton 80/5 MFD, 450V, Round 1 Larger compressors and light commercial equipment 5 MFD, 450V, Round (Single Run) 2 Standalone condenser fan motors, pool pumps, small single-phase motors 7.5 MFD, 450V, Round (Single Run) 2 Standalone condenser fan motors, pool pumps, small single-phase motors Common Problems This Kit Solves 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 Needing a specific capacitor rating on the spot without a return trip to the supply house 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.

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 XPDC40X5-450R Dual Run Capacitor (40/5 MFD, 450V, Round) The XPARTCO XPDC40X5-450R 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 40 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 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. 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 Cross Reference Information Part numbers can change over a product's lifecycle as manufacturers update designs or release new appliance models. For your convenience, we've included any known superseded, alternate, or cross-reference part numbers that match this item. Replaces Part Numbers 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.

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.
