A single run capacitor provides the continuous electrical charge needed to keep either the compressor or the condenser fan motor running at peak efficiency. When this capacitor fails, you'll notice symptoms such as a humming unit that won't start, a fan or compressor that stops shortly after startup, or a system that trips the breaker due to excessive amp draw. Replacing this component promptly prevents costly secondary damage to the motor or compressor.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-matched MFD rating and 370V\/440V rated | Round or oval case as factory-specified | Tight ±3% tolerance for reliable motor performance | Verify exact MFD value on your unit's data plate before ordering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This genuine OEM capacitor is manufactured to Payne's exact factory tolerances.
