OEM Carrier Single Run Capacitor P291-5003 for Model 09DK028600

This OEM single run capacitor (part number P291-5003) is the factory-specified replacement for the Carrier 09DK028600 system. The run capacitor provides the continuous phase-shifted electrical charge that keeps the motor running smoothly after startup. When this capacitor weakens or fails, you'll notice symptoms such as a humming motor that won't spin, intermittent short-cycling, higher-than-normal amp draw, or complete failure of the condenser fan or compressor motor to start.

• Specs: Single run capacitor | Factory OEM-matched MFD rating | 370V/440V rated | Cylindrical case | ±3% tight tolerance for precision motor protection
• OEM vs Generic: This is a genuine Carrier OEM part (P291-5003), manufactured to exact factory tolerances. Generic alternatives often run ±10% MFD deviation, which accelerates motor winding wear and can shorten compressor life significantly over time.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to confirm full discharge. Photograph all wiring connections before removal.
• Warranty: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Engineered specifically for the Carrier 09DK028600. Always verify the MFD rating and voltage on your unit's data plate or existing capacitor before ordering to ensure an exact match.
