The dual run capacitor provides the starting torque and continuous run support for both the compressor and the condenser fan motor from a single component. When this capacitor begins to fail, you'll notice symptoms such as a humming sound with no motor movement, the condenser fan spinning slowly or not at all, the compressor failing to start, or the system tripping on high-pressure lockout due to insufficient cooling. Replacing this capacitor promptly protects your compressor — the most expensive component in the system — from the damaging effects of low-voltage operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 45+5 MFD (microfarad) | 440V rated | Round capacitor case | Factory-matched ±3% tolerance | OEM part number P291-4554RS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM capacitor is wound and tested to Payne's exact factory specifications. Generic alternatives commonly ship at ±10% MFD tolerance, which increases heat buildup in motor windings and shortens compressor service life significantly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor before touching terminals (use an insulated resistor or discharge tool).
