The run capacitor remains in the circuit continuously during motor operation, stabilizing voltage and ensuring the fan motor runs efficiently. When it degrades or fails, you'll typically notice a humming sound with no motor movement, the unit blowing warm air, short cycling, or the system failing to start altogether. Visible swelling or oil residue on the capacitor body is also a clear sign of failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (microfarad) | 370 VAC | Oval case | 50\/60 Hz | OEM part numbers: P291-0403 (4 MFD 370V), P291-1003 (10 MFD 370V), P291-1503 (15 MFD 370V) — select the MFD rating that matches your unit's data plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Totaline\/Carrier OEM capacitor tested to 60,000 service hours with 100% electrical testing at the factory and UL-approved pressure-sensitive interrupter for safe failure.
