OEM Carrier Single Run Capacitor 50 MFD 370V for Model 09DK028500

This OEM single run capacitor is the factory-specified replacement for the Carrier 09DK028500, carrying OEM part number P291-5003. A single run capacitor provides the continuous phase-shifted current that keeps your compressor motor running efficiently after startup. When this capacitor weakens or fails, you may notice the compressor humming but failing to start, intermittent short-cycling, tripped breakers, or a complete no-cool situation — all classic signs of capacitor failure that this direct OEM replacement resolves.

• Specs: 50 MFD (microfarad) | 370V rated (compatible with 370V and 440V applications) | Oval case form factor | Factory-matched ±5% tolerance | CBB65-V dielectric fluid, UL recognized
• OEM vs Generic: This OEM capacitor is manufactured to Carrier's exact factory tolerances. Generic aftermarket units commonly run at ±10% MFD variance, which accelerates motor winding stress and shortens compressor service life — especially under heavy summer load cycles.
• Install difficulty: 2/5 — Always discharge the capacitor before handling (use a 20kΩ resistor or insulated screwdriver across terminals). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode to verify). Always photograph the existing wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Engineered as a direct OEM drop-in fit for Carrier model 09DK028500. Verify the MFD rating and voltage on your unit's data plate before ordering. Also fits select Bryant and Payne models sharing the same P291-5003 specification. Not sure it fits? Our HVAC parts specialists verify fitment before every order — just ask.
