This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8JAA036110ADJA gas furnace blower motor circuit. The run capacitor maintains a steady phase-shifted current to keep the blower motor spinning efficiently after startup. When this capacitor weakens or fails, you'll typically notice the blower motor humming without turning, running sluggishly, overheating, or failing to start altogether — symptoms that can trigger nuisance limit-switch trips and comfort complaints on even the coldest nights.
Compatibility: Designed for the Carrier PG8JAA036110ADJA gas furnace blower motor. Verify the MFD rating and voltage stamped on your existing capacitor's label before ordering — mismatched MFD values will damage the motor. Note: P291-1003 has been updated by Carrier to successor part P291-1004 (370/440V, 10 MFD) which ships as the current OEM equivalent. Questions about fitment? Our HVAC parts specialists verify compatibility before you order — call or chat today.
