A single run capacitor maintains a continuous phase-shift in the motor winding to keep the motor running at rated torque and efficiency. When it degrades or fails, common symptoms include a loud humming with no motor movement, intermittent motor start failures, or the system tripping on thermal overload shortly after startup.\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 hermetically sealed case | ±5% tolerance per OEM specification — verify exact MFD on your unit data plate before ordering\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 tolerances. Generic alternatives often deviate ±10% MFD, which accelerates motor winding wear, reduces efficiency, and can shorten compressor or fan motor life significantly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before removing terminals (use an insulated resistor or discharge tool). Tools needed: 1\/4\" nut driver, needle-nose pliers, multimeter (capacitance mode).
