A dual run capacitor stores and delivers the electrical charge required to start and continuously run both the compressor and the condenser fan motor from a single round can. When this capacitor fails, you'll typically experience a loud hum with no motor movement, the unit short-cycling within seconds of startup, or the condenser fan spinning weakly or not at all — all signs of imminent compressor damage if left unaddressed. A second OEM part number for this unit, \u003cstrong\u003eP291-1503\u003c\/strong\u003e, covers the single run capacitor variant; confirm your existing capacitor's MFD ratings before ordering.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 35+5 MFD (microfarad) | 440V rated | Round case | ±6% tolerance | 50\/60 Hz | 10,000 AFC | Castor oil protected | No PCBs | UL approved\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM capacitor meeting exact factory specifications. Generic capacitors often carry a ±10% MFD tolerance versus the OEM ±6%, leading to accelerated motor and compressor wear over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before touching any terminals.
