The run capacitor provides the continuous phase-shifted current required to keep the condenser fan motor or blower motor spinning efficiently once started. When this capacitor begins to fail, you may notice the motor humming without spinning, struggling to reach full speed, drawing excess current, or shutting down on thermal overload — all signs of imminent motor failure if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (microfarad) | 370 VAC rated | Oval case | Factory-matched ±5% tolerance | OEM Part Numbers: P291-0403 \/ P291-1503\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This Carrier Totaline OEM capacitor is \u003cstrong\u003ereliability-tested to 60,000 service hours\u003c\/strong\u003e and subjected to 100% electrical testing at the factory.
