Carrier 331055-706 Pressure Switch
The Carrier 331055-706 High Pressure Switch is a critical safety component designed for precise refrigerant circuit monitoring in high-output HVAC systems. Engineered as a manual reset pressure switch, it functions on a 670/470# pressure rating, meaning it trips at 670 PSI and allows for a manual reset once the pressure drops back to 470 PSI. This OEM HVAC replacement part is built for durability in high-demand environments, ensuring the compressor is protected from discharge pressures that could lead to catastrophic failure. For technicians performing Carrier AC service or repair on compatible rooftop units and split systems, this switch provides the exact electrical specifications required to maintain system integrity. The 1/4-inch female flare fitting allows for a secure, leak-free connection to the service port, while the robust internal contacts ensure consistent HVAC pressure switch troubleshooting results and long-term reliability under varying thermal loads.
Key Benefits- System Protection: Precisely calibrated 670 PSI cutout prevents compressor damage due to condenser fan failure or blocked coils.
- Manual Reset Security: Forces a technician inspection of the refrigerant cycle before the system can resume operation, preventing repeated short-cycling under fault conditions.
- Direct OEM Fit: Ensures exact compatibility with factory wiring harnesses and mounting positions, reducing labor time during HVAC compressor protection upgrades.
- High-Pressure Tolerance: Specifically designed for modern high-pressure refrigerants, maintaining set-point accuracy across a wide range of ambient temperatures.
What causes the 331055-706 high pressure switch to trip?
Common culprits include a failed condenser fan motor, excessively dirty condenser coils, or an overcharge of refrigerant. Since this is a manual reset switch, you must physically depress the reset button after the pressure drops below 470 PSI and the underlying fault is corrected.
Can I bypass this switch for testing purposes?
While a temporary jumper can be used to diagnose a faulty switch, the system should never be left operational without a functional high pressure limit. Operating without this safety control risks permanent damage to the compressor and potential rupture of the refrigerant lines.
Is the 331055-706 compatible with R-410A systems?
Yes, the 670 PSI trip point is specifically engineered for the higher operating pressures associated with R-410A and similar high-pressure refrigerants used in industrial and residential cooling applications.
