A single run capacitor provides the continuous electrical charge required to keep either the compressor or the condenser fan motor running at peak efficiency after startup. When this component fails, you'll typically notice a loud humming with no motor movement, intermittent short-cycling, or a complete failure of the condenser fan or compressor to start — often causing the system to trip on high-pressure lockout within minutes.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-matched MFD rating | 370V or 440V rated (verify on unit data plate) | Round or oval case | Factory ±5% tolerance for precise motor protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM capacitor is manufactured to Payne's exact factory tolerances.
