Nordyne 664345R TXV Valve

The Carrier P291-3053RS Run Capacitor is a mission-critical 30/5 MFD dual run capacitor designed for high-performance HVAC motor applications in Carrier, Bryant, and Payne residential condenser units. Rated at 370 VAC with a frequency of 50/60 Hz, this round dual run capacitor facilitates the distinct electrical phases required to drive both the hermetic compressor and the condenser fan motor from a single, space-optimized component. Built with non-PCB dielectric fluid and housed in a durable aluminum casing, this replacement capacitor includes an internal UL-approved pressure-sensitive interrupter to safely disconnect the circuit in the event of internal failure, preventing casing rupture. As a veteran tech knows, while this unit is rated for 370V, it is backward compatible with systems requiring 30/5 MFD performance specs. This HVAC electrical part features standard 1/4-inch male quick-connect terminals clearly labeled for Herm, Fan, and Common connections, ensuring accurate field wiring and reduced diagnostic time when troubleshooting hard-start cycles or humming motors.

• How do I test a 30/5 MFD dual run capacitor?
• Is the Carrier P291-3053RS compatible with Bryant AC units?
• What are the signs of a failing 370V run capacitor?

• OEM Compatibility: Exact replacement for multiple Carrier and Bryant part numbers including HC93CA031 and P281-3053.
• Dual-Purpose Design: Manages both the 30 MFD compressor load and the 5 MFD fan motor output in one round-can footprint.
• Industrial Protection: Features a 10,000 AFC (Available Fault Current) rating and castor oil protection for stable dielectric performance between -40°C and 70°C.
• Standardized Terminals: Equipped with quad-post terminals for the "C" (Common) and dual-post for "Herm" and "Fan" to accommodate various wiring harness configurations.

• Can I use a 440V capacitor if the 370V P291-3053RS is out of stock? Yes, in HVAC applications, you can always go up in voltage rating (e.g., using a 440V in place of a 370V), but you must never use a lower voltage rating or change the microfarad (MFD) value.
• Why is my capacitor bulging at the top? Physical swelling is a clear indication that the internal pressure-sensitive interrupter has tripped due to age or overheating. The component must be replaced immediately to restore system operation.
• Does it matter which way the wires go? Yes. Terminal "H" must connect to the compressor, "F" to the fan motor, and "C" to the common power leg. Reversing these will likely result in motor failure or immediate tripping of the breaker.
