A single run capacitor maintains a continuous phase shift to keep the blower motor running at peak efficiency after startup. When this capacitor fails, you'll notice symptoms such as a humming motor that won't spin, intermittent blower operation, weak airflow, or the system shutting down shortly after startup due to motor overload. Replacing a failed capacitor promptly protects the blower motor from heat damage and costly secondary failures.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory-matched MFD rating | 370V\/440V rated | Round or oval case | ±5% OEM 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 capacitor built to exact factory specifications.
