Carrier P291-8073RS Capacitor
The Carrier P291-8073RS is a heavy-duty 80/7.5 MFD 370V dual round run capacitor designed for high-demand HVACR applications. As the direct OEM updated version for HC98JA082, this component provides the essential phase-shift and torque required for dual-motor systems, typically supporting both the compressor (80 MFD) and the condenser fan motor (7.5 MFD). Engineered for durability in high-ambient environments, it features a 10,000 AFC (Available Fault Current) safety rating and is EIA-456 compliant, ensuring 60,000 service hours of reliable performance. Its round aluminum case is oil-filled for superior heat dissipation, making it a critical AC capacitor replacement for Carrier, Bryant, and Payne condensing units. Technicians should note that while rated at 370V, it can be utilized in systems requiring 370/440V compatibility as an upgrade over standard 370V units, provided the microfarad ratings match. For contractors, this dual run capacitor 80+7.5 is a standard truck-stock item for restoring HVAC motor start-up and maintaining compressor efficiency.
Key Benefits- OEM Compatibility: Specifically engineered to replace HC98JA082 and P291-8073R in Carrier-family equipment.
- High-Temperature Resilience: Rated for operation from -40°C to 70°C to prevent premature failure during peak summer loads.
- Safety Engineered: Features a moisture-resistant non-PCB oil and a pressure-sensitive internal interrupter for circuit protection.
- Dual-Action Design: Consolidates two capacitors into one round can to save space in the control box while powering the Herm and Fan circuits.
- Standardized Terminals: Equipped with 1/4-inch quick-connect terminals clearly labeled for Common, Hermetic, and Fan connections.
Can I use a 440V capacitor if my original was 370V?
Yes. You can always use a higher voltage rating (e.g., replacing 370V with 440V), as it indicates a thicker dielectric layer and higher insulation strength. However, you must never use a lower voltage rating than the original specification.
How do I identify a failing P291-8073RS?
Technicians should look for physical signs of "mushrooming" or bulging on the top cap. Electrically, if the capacitance reading on a multimeter falls outside the +/- 6% tolerance range, the dual run capacitor must be replaced to prevent compressor short-cycling.
What does the 80/7.5 MFD rating signify?
This is a dual-rated component. The 80 MFD (microfarad) side is designed for the high-torque demand of the AC compressor, while the 7.5 MFD side provides the necessary current for the condenser fan motor.
