This OEM single run capacitor is the factory-specified replacement for the Carrier YAC3080YAC106 air conditioning system, cross-referencing original part number P291-3503. The run capacitor provides the sustained electrical energy that keeps the compressor or condenser fan motor spinning efficiently after startup. When this component weakens or fails, you'll typically notice the unit humming without starting, tripping the breaker, short-cycling, or the outdoor fan refusing to spin — all classic signs of capacitor failure that will only worsen without replacement.
Compatibility: Designed for Carrier model YAC3080YAC106. OEM part number P291-3503 (superseded). Always verify the MFD rating and voltage stamped on your existing capacitor's data label before ordering to confirm an exact match. Have a question about fitment? Our HVAC parts specialists verify compatibility before you buy — order with confidence and get it shipped today.
