A single run capacitor maintains the continuous phase-shifted current needed to keep your blower or fan motor running at peak efficiency. When this component fails, you'll typically notice symptoms such as a humming sound with no motor movement, intermittent shutdowns, or a blower fan that refuses to start — leaving your system unable to circulate conditioned air through your home.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-matched MFD rating | 370V\/440V rated (verify on unit data plate) | Oval or round case | Factory ±3% capacitance tolerance for precise motor protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part, engineered to exact factory specifications.
