Carrier P291-0504 Run Capacitor
The Carrier P291-0504 Run Capacitor is a high-performance genuine OEM replacement engineered for critical motor support in residential and commercial HVAC units. Rated at 5 MFD (microfarads) and 440V, this oval run capacitor provides the Phase-Shift required to maintain optimal torque and energy efficiency for fan motors, inducer motors, and small compressors. Built with metallized polypropylene film, it is designed to operate in demanding environments, supporting both 50Hz and 60Hz frequencies with a tolerance of +/- 6%.
As a veteran-grade HVAC capacitor, the P291-0504 serves as a direct P291-0504 cross reference for discontinued or older models including P291-0503, HC91CA005, and 1178116. Its 440-volt insulation rating allows it to safely replace 370V alternatives, providing a more robust electrical buffer against voltage surges. The unit features standard 1/4-inch male quick-connect terminals and a pressure-sensitive interrupter (up to 10,000 AFC) to ensure the circuit breaks safely in the event of an internal fault, preventing housing rupture.
Key Benefits for Contractors:- Universal Compatibility: Field-proven to replace Carrier, Bryant, and Payne part numbers such as HC91CA005, HC91CL005, and P291-0503.
- Enhanced Durability: Rated for up to 60,000 service hours, outperforming generic aftermarket alternatives in high-cycling applications.
- Technical Safety: Integrated internal pressure interrupter meets UL standards for fault protection.
- Form Factor: The compact oval capacitor design ensures a precise fit in tight electrical service panels.
Can I use a 440V capacitor to replace a 370V unit?
Yes. In HVAC applications, you can always go up in voltage rating (from 370V to 440V) as it provides better insulation, but you must never go down. The 5 MFD capacitance must remain identical to the motor's nameplate requirements.
Why is my capacitor bulging or leaking?
Physical deformation or fluid leakage indicates an internal failure, usually due to age or excessive heat. A failed motor run capacitor will prevent the motor from reaching full RPM or starting at all, leading to potential motor burnout.
Is the P291-0504 a "Start" or "Run" capacitor?
This is a run capacitor designed to stay in the circuit while the motor is operational. Unlike start capacitors, which are usually plastic-cased and high-MFD, this oil-filled metal unit is built for continuous duty.
