OEM Carrier Single Run Capacitor P291-0753 for Model YAC42110YACX202AK

This is the factory-specified OEM single run capacitor (part number P291-0753) for the Carrier YAC42110YACX202AK split-system air conditioner. The run capacitor provides a continuous phase-shifted current to keep the compressor or fan motor running smoothly and efficiently. When this capacitor degrades or fails, you'll typically notice symptoms such as a humming motor that won't spin up, the system short-cycling shortly after startup, unexpectedly high electric bills, or a complete no-start condition where the outdoor unit sits silent while the thermostat calls for cooling.

• Specs: OEM Single Run Capacitor | Part No. P291-0753 | Factory-matched MFD and voltage rating | Round case design for easy drop-in replacement
• OEM vs Generic: This genuine OEM capacitor is manufactured to Carrier's exact tolerance specifications (typically ±3% MFD). Aftermarket alternatives commonly run ±6–10% tolerance, which accelerates motor wear, reduces efficiency, and can shorten compressor life significantly.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals (use a 20,000-ohm resistor bleed tool or insulated screwdriver). Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify capacitance post-install. Photograph all wiring before disconnecting. Turn off all power at the disconnect box before beginning.
• Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship the same business day directly from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier YAC42110YACX202AK condensing unit. Always verify the MFD value and voltage rating on your unit's data plate or existing capacitor before ordering to ensure an exact match. Not sure about fitment?
