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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Single Run Capacitor | Factory-matched MFD rating | 370V \/ 440V compatible | Round capacitor case | ±5% tolerance per OEM specification\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part — factory-matched to exact MFD and voltage tolerances required by the PG8MAA048110AAJA.
