OEM Carrier Dual Run Capacitor 40+5 MFD 440V for Model PH10JA04200GAGAA

This OEM dual run capacitor (part# P291-4054RS) is the factory-specified replacement for the Carrier PH10JA04200GAGAA heat pump condensing unit. The dual run capacitor stores and releases the electrical charge required to start and sustain both the compressor and condenser fan motor in a single round can. Common failure symptoms include a loud humming with no motor movement, the unit short-cycling within minutes of startup, or a complete failure to turn on — especially during peak summer heat when capacitors are under the most thermal stress. A companion start capacitor (P281-8806) is also available for this unit and is recommended for inspection whenever the dual run capacitor is replaced.

• Specs: 40+5 MFD (microfarad) | 440V rated | Round case | ±6% tolerance | 50/60 Hz | 10,000 AFC | Castor oil protected | No PCB | RoHS compliant
• OEM vs Generic: This is a genuine Carrier OEM part manufactured to exact factory tolerances. Generic aftermarket capacitors often carry ±10% MFD tolerance, which accelerates compressor and fan motor wear and can shorten system life — particularly in heat pump applications that run year-round.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance mode. Photograph all wiring before disconnecting. This is a common DIY repair for experienced homeowners.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for Carrier model PH10JA04200GAGAA heat pump condensing units. Also replaces legacy Carrier part numbers HC98KA041 and P291-4053RS.
