The run capacitor provides a continuous phase-shifted current to keep the compressor or fan motor running smoothly after startup. When this capacitor weakens or fails, you'll commonly experience a humming compressor that won't start, intermittent short-cycling, or a complete loss of cooling — symptoms that point directly to capacitor failure before any other component is condemned.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 35 MFD (microfarad) | 370\/440V rated | Oval case | ±5% factory tolerance | Non-PCB dielectric fluid | UL approved\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier\/Totaline OEM capacitor, factory-matched to exact MFD tolerance.
