OEM Carrier Single Run Capacitor 3 MFD 250V for Model PG9MAA024040AFKA

This is the genuine OEM Carrier single run capacitor (part #HC91PD001), factory-specified for the Carrier PG9MAA024040AFKA gas furnace. The run capacitor stores and delivers the precise electrical charge required to start and continuously run the draft inducer blower motor. When this capacitor begins to fail, symptoms include a noisy or humming inducer motor, motor overheating, erratic cycling, or a blower that fails to start entirely — often triggering a pressure switch fault and locking out the furnace before ignition.
