The run capacitor stores and releases the precise electrical charge needed to keep the blower motor running smoothly and efficiently. When this capacitor degrades or fails, you'll notice symptoms such as the motor humming but failing to start, intermittent short-cycling, sluggish blower performance, or a complete failure to run — leaving you without conditioned air when you need it most.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 15 MFD (microfarad) | 370V rated | Oval case | 50\/60 Hz | UL approved current interrupter | Non-PCB dielectric fluid | Factory-matched ±5% tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier\/Totaline OEM capacitor (P291-1503), manufactured to exact factory tolerances. Generic aftermarket capacitors often deviate ±10% MFD, which accelerates motor winding stress and significantly shortens motor life over repeated start cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before handling any terminals.
