Carrier P291-1004 Run Capacitor
The Carrier P291-1004 Run Capacitor is a 10 MFD 440V AC oval capacitor engineered for precision motor support in high-performance Carrier, Bryant, and Payne HVAC systems. As a veteran-grade OEM HVAC replacement part, it is the direct functional successor to the P291-1003, built to withstand the thermal and electrical rigors of continuous compressor and fan motor operation. This metallized polypropylene film capacitor is designed for high-efficiency heat dissipation and stable capacitance, ensuring the HVAC motor start and run cycles remain within tight manufacturer tolerances. By maintaining the correct phase shift for the motor windings, this 10 microfarad capacitor protects sensitive internal components from premature winding failure and excessive amp draw. Designed for 440V applications, this component is also backward compatible with 370V systems, providing a robust overhead for voltage fluctuations in demanding residential and commercial environments.
Key Benefits for HVAC Professionals
- Universal Compatibility: Serves as the direct OEM replacement for P291-1003, ensuring exact physical fitment and electrical alignment within Carrier-family equipment.
- Enhanced Durability: Rated for 440 VAC, offering superior dielectric strength compared to standard 370V alternatives.
- Optimized Motor Efficiency: Maintains the required 10 MFD capacitance with a strict ± tolerance to prevent overheating and erratic motor behavior.
- Heavy-Duty Construction: Features a leak-proof oval aluminum casing with standard 1/4-inch quick-connect terminals for rapid field installation.
- Environmental Resilience: Engineered to operate reliably in high-ambient temperature conditions common in condenser cabinets and air handlers.
Common Questions
Can I use the P291-1004 to replace a 370V capacitor?
Yes. This 440V run capacitor can safely replace 370V units with the same 10 MFD rating, as the voltage rating indicates the maximum threshold the capacitor can handle without failure.
What does it mean if the label doesn't say "Carrier"?
Carrier sources high-grade electrical components from specialized manufacturers like Genteq or Proteus. This remains a factory-authorized part that meets all original equipment performance specifications regardless of the brand stamp on the casing.
Why is my capacitor bulging or leaking?
Physical deformation or oil leakage typically indicates a voltage spike or internal dielectric breakdown. A failed run capacitor should be replaced immediately to prevent permanent damage to the compressor or blower motor windings.
