Capacitors store and release the electrical charge required to start and run the compressor and condenser fan motor. A failing dual run capacitor typically causes a loud hum with no motor movement, intermittent short-cycling, or a compressor that trips on thermal overload. A failing start capacitor prevents the compressor from starting under load, often resulting in a locked rotor condition and tripped breakers. Replacing both at the same time is widely recommended by HVAC technicians to avoid a repeat service call.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers \u0026amp; Specs:\u003c\/strong\u003e Dual Run Capacitor P291-2553RS | Start Capacitor P281-1896S | Factory-matched MFD tolerance ±3% | 370V\/440V rated as specified by Carrier for this model\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to exact Carrier factory tolerances. Aftermarket alternatives frequently deviate ±10% MFD, which accelerates motor winding wear and can shorten compressor life significantly — costing far more in the long run than the price difference at purchase.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always discharge capacitors fully before handling — stored charge can be lethal even with power off.
