The run capacitor stores and releases the precise electrical charge needed to keep the condenser fan motor or compressor running smoothly after startup. A failing run capacitor will typically cause the motor to hum loudly without turning, overheat and trip on thermal overload, or cause the unit to short-cycle — leaving your system unable to maintain setpoint on hot days when you need it most.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50 MFD (microfarad) | 370V rated (440V compatible as an upgrade) | Oval case | ±5% factory tolerance | Replaces OEM part P291-5003\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM-spec capacitor is manufactured to Carrier's exact MFD and voltage tolerances.
