The run capacitor maintains a continuous phase shift in the motor winding to keep the condenser fan motor or blower motor running at full torque and efficiency. When the capacitor weakens or fails, the motor may hum without spinning, draw excessive current, overheat, or fail to start entirely — often causing the entire system to shut down on a thermal overload.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (microfarad) | 370 VAC rated | Oval case | ±5% factory tolerance | 50\/60 Hz | OEM Part Numbers: P291-0403 \/ P291-1503\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier\/Totaline OEM capacitor, tested to 60,000 service hours with 100% electrical inspection at the factory. Generic capacitors often run at ±10% MFD tolerance, accelerating motor wear and reducing equipment lifespan.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Discharge the old capacitor fully before touching any terminals (use an insulated resistor or discharge tool).
