OEM Carrier Single Run Capacitor P291-5003 for Model 09DK024500

This OEM single run capacitor (part number P291-5003) is the factory-specified replacement for the Carrier 09DK024500 system. A run capacitor provides the continuous phase-shifted current needed to keep a single motor — either the compressor or the condenser fan — running efficiently after startup. When this capacitor weakens or fails, you'll typically notice the motor humming but not spinning, the system tripping on thermal overload, or the unit short-cycling within minutes of startup.

• Specs: Single run capacitor | Factory-matched MFD and voltage rating | Round or oval case per OEM specification | ±3% tolerance for precise motor performance
• OEM vs Generic: This is a genuine OEM Carrier part (P291-5003), built to exact factory tolerances. Generic alternatives often carry ±10% MFD variance, which increases motor winding stress and can shorten compressor or fan motor lifespan significantly.
• Install difficulty: 2/5 — Always discharge the capacitor fully before removing any terminals (use an insulated resistor or dedicated discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify capacitance. Photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship the same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier model 09DK024500. Always cross-reference the MFD rating and voltage listed on your unit's data plate or the original capacitor before ordering to confirm an exact match. Have a question about fitment?
