A run capacitor provides the continuous phase-shifted electrical charge required to keep the motor running efficiently after startup. When this capacitor begins to fail, symptoms include a loud humming noise with no motor movement, intermittent short-cycling, reduced system efficiency, or a complete failure of the condenser fan or blower motor to start — often leaving you with warm air and a rising utility bill.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | OEM part number P291-0753 | Factory-matched MFD and voltage rating | Round or oval case per OEM specification | ±5% tolerance for precise motor protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM capacitor built to exact factory tolerances.
