The run capacitor stores and releases electrical charge to sustain the condenser fan motor during operation. When it degrades, you'll typically notice symptoms such as a humming or buzzing sound with no fan movement, the unit struggling to start, blowing warm air, or short-cycling on and off — all classic signs of a failed run capacitor that should be replaced promptly to prevent downstream motor damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (microfarad) | 370V rated | Oval case | Metallized polypropylene film construction | ±5% factory tolerance | RoHS compliant | Replaces P291-0403, P291-1503\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM Totaline\/Carrier capacitor is built to exact factory tolerances and is UL approved with a patented pressure-sensitive interrupter.
