A run capacitor provides the continuous phase-shifted electrical current needed to keep a single motor — typically the condenser fan or blower motor — running efficiently after startup. When this capacitor weakens or fails, you'll notice symptoms such as a humming motor that won't spin, sluggish motor startup, system short-cycling, 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 on unit data plate) | Round or oval case | OEM tolerance ±3% for precision motor protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, manufactured to exact factory specifications. Generic capacitors often carry ±10% MFD tolerance, which increases motor operating temperature, accelerates winding wear, and can void equipment warranties — making OEM the smart long-term choice.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before handling any terminals (use an insulated resistor or discharge tool). Tools needed: 1\/4\" nut driver, needle-nose pliers, and a multimeter to confirm the old capacitor has failed.
