The run capacitor provides a continuous phase-shifted current to keep the fan motor or compressor running smoothly after start-up. When it degrades or fails, symptoms include a humming motor that won't spin, intermittent cycling, or a system that trips on thermal overload due to the motor drawing excessive amperage without proper capacitive support.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 4 MFD (microfarad) | 370 VAC | Oval case | Metallized polypropylene film construction | ±5% capacitance tolerance | 50\/60 Hz rated | RoHS compliant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM Carrier\/Totaline unit is subjected to 100% electrical testing at the factory and features a UL-approved patented pressure-sensitive interrupter for safe failure. Generic aftermarket capacitors often skip individual unit testing and use lower-grade dielectric film, leading to premature failure and potential motor damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the old capacitor before handling (use an insulated screwdriver across terminals). Tools needed: flathead screwdriver, needle-nose pliers, multimeter (capacitance mode). Photograph wiring orientation before removal. Match MFD and voltage exactly — never substitute a higher MFD rating on a run capacitor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
