OEM Carrier Single Run Capacitor 50 MFD 370V for Model 09DK044500

This is the factory-specified OEM single run capacitor for the Carrier 09DK044500, sold under Carrier/Totaline OEM part number P291-5003. The run capacitor provides the continuous phase-shifted electrical current that keeps the compressor motor spinning efficiently after startup. A failing run capacitor is one of the most common causes of HVAC service calls — symptoms include a loud hum with no compressor start, the unit tripping on thermal overload, warm air blowing from a running system, or the compressor drawing excessive amperage and shutting down on high-limit protection. Replacing the capacitor at first sign of failure prevents costly compressor damage.

• Specs: 50 MFD (microfarad) | 370V rated | Oval case | CBB65-V rated | ±5% factory tolerance | Non-PCB dielectric fluid | UL-approved pressure-sensitive interrupter
• OEM vs Generic: This OEM Carrier/Totaline capacitor is manufactured to exact factory tolerance (±5% MFD), ensuring proper motor current and compressor longevity. Generic aftermarket units often ship at ±10% tolerance, which accelerates motor winding wear and can void compressor warranties.
• Install difficulty: 2/5 — Always discharge the capacitor before handling using an insulated resistor or discharge tool. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Photograph all wiring connections before removal. Replacement typically takes 15–30 minutes.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for Carrier model 09DK044500. Always verify the MFD rating and voltage printed on your existing capacitor's label before ordering — mismatched MFD values will cause motor damage. Our fitment team is available to confirm compatibility before you buy.
