The run capacitor maintains a continuous phase-shifted current to keep the blower motor spinning at rated speed and efficiency. When it degrades or fails, expect symptoms such as a blower motor that hums but won't start, weak airflow due to sluggish motor rotation, or a system that trips on thermal overload shortly after startup. Replacing this capacitor promptly protects the blower motor from overheating and costly secondary damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 7.5 MFD (microfarad) | 370V rated | Oval case | ±5% factory tolerance | OEM part number P291-0753 (superseded by P291-0754)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier capacitors are manufactured to exact factory MFD and voltage tolerances, ensuring the blower motor draws correct current from first start.
