OEM Carrier Single Run Capacitor P291-1003 for Model PG8MAA048110AAJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8MAA048110AAJA gas furnace. The run capacitor maintains a continuous phase-shifted current to keep the blower motor running at peak efficiency. When a run capacitor fails, the blower motor may hum without spinning, draw excess current, overheat, or cause the furnace to short-cycle — leaving you without heat or proper airflow. Replacing the capacitor promptly protects the blower motor from costly burnout.
