Unlike a dual run capacitor, a single run capacitor is dedicated solely to the compressor motor, storing and releasing the precise electrical charge needed to start and keep it running efficiently. Common failure symptoms include a humming compressor that won't start, frequent short-cycling, or a system that trips the breaker repeatedly — all signs the capacitor can no longer hold its rated charge.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50 MFD (microfarad) | 370V rated | Round case | Factory-matched ±5% tolerance | OEM Part Number: P291-0503\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This genuine OEM capacitor is manufactured to exact Payne factory tolerances.
