The run capacitor maintains a continuous phase-shifted current to keep the blower motor running at peak efficiency. When it begins to fail, you may notice the blower motor struggling to start, humming without spinning, overheating, or shutting down shortly after startup — all signs of a capacitor that can no longer hold its charge.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory-matched MFD rating | Rated voltage per OEM specification | Oval or round case per original design | ±3% tolerance for precision motor protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier capacitor built to exact factory tolerances. Generic aftermarket capacitors frequently carry a ±10% MFD variance, which accelerates motor winding wear, reduces efficiency, and shortens the service life of your blower motor significantly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before handling any terminals.
