A run capacitor maintains a continuous phase-shifted current to keep a single motor — typically the condenser fan or blower motor — running at peak efficiency. When this capacitor fails, you'll notice symptoms such as a humming motor that won't spin up, intermittent shutdowns due to motor overload, or a complete no-start condition on the affected motor circuit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory-matched MFD rating | 370V or 440V rated (verify against unit data plate) | 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 OEM unit is manufactured to Carrier's exact electrical specifications.
