The run capacitor maintains a continuous phase-shifted current to keep the fan motor running at peak efficiency after startup. When it degrades or fails, you'll notice symptoms such as a buzzing or humming motor that won't spin, intermittent shutdowns, or a condenser\/blower fan that draws excessive amperage and overheats — often leading to nuisance tripping of the motor's thermal overload protector.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory-matched MFD rating | 370V\/440V rated | Cylindrical case | OEM-spec ±5% tolerance for motor longevity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part — not an aftermarket substitute.
