Unlike a dual run capacitor, the single run capacitor remains in the circuit continuously throughout motor operation, stabilizing voltage and ensuring efficient, reliable motor performance. When this capacitor fails, you'll typically experience a humming or buzzing sound with no motor movement, a fan or blower that fails to start, or a unit that short-cycles and shuts off shortly after attempting to start. Prompt replacement prevents secondary motor damage caused by locked-rotor current draw.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (microfarad) | 370 VAC rated | Oval case | ±5% capacitance tolerance | 50\/60 Hz | Replaces OEM part numbers P291-0403, P291-1003, and P291-2503\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Totaline-branded OEM capacitor manufactured to factory tolerance specifications, built with high-grade metallized polypropylene film and 100% electrically tested before shipment. Generic alternatives often ship with ±10% MFD tolerance, which accelerates motor wear and can void equipment warranties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always shut off power at the disconnect and allow 5 minutes for residual charge to dissipate before touching terminals.

Always cross-reference the MFD and voltage rating on your unit's data plate before ordering — voltage rating must match or be higher (e.g., a 440V-rated capacitor is acceptable in a 370V application). This part also cross-references OEM numbers P291-1003 and P291-2503. Questions about fitment?
