OEM Carrier Single Run Capacitor 50 MFD 370V for Model 09DK044100

This OEM single run capacitor is the factory-specified replacement for the Carrier 09DK044100, cross-referencing OEM part number P291-5003. 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.

• Specs: 50 MFD (microfarad) | 370V rated (440V compatible as an upgrade) | Oval case | ±5% factory tolerance | Replaces OEM part P291-5003
• OEM vs Generic: This OEM-spec capacitor is manufactured to Carrier's exact MFD and voltage tolerances. Off-brand capacitors often drift beyond ±10% MFD, increasing motor winding stress and accelerating compressor wear over time.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal.
• Warranty & Shipping: 1-year OEM warranty coverage. In stock and ships the same business day from our warehouse — get your system back online fast.
