This is the factory-original single run capacitor (OEM part number P291-1003) designed as a direct replacement for the Carrier GB3AAV060135ACJA gas furnace. The run capacitor provides the sustained phase-shifted electrical charge that keeps the blower motor running efficiently after startup. When this capacitor degrades or fails, you'll notice symptoms such as the blower motor humming without spinning, sluggish motor startup, intermittent blower operation, or the furnace shutting down on a thermal overload due to a motor struggling under increased electrical load.
Compatibility: Engineered specifically for the Carrier GB3AAV060135ACJA gas furnace blower motor circuit. Always verify the MFD and voltage rating printed on your existing capacitor or the unit's data plate before ordering to confirm an exact match. Our HVAC parts specialists are available to verify fitment before you complete your purchase — order with confidence and get your system back up and running today.
