ClimateMaster 13B0055N01 Pressure Switch

The ClimateMaster 13B0055N01 Pressure Switch is a critical safety component designed to protect refrigeration and HVAC compressors from catastrophic failure due to loss of charge or restricted flow. This low pressure switch 35-60# monitors the suction line, ensuring the system remains within safe operating parameters. As a genuine OEM replacement part, it ensures precise calibration for ClimateMaster heat pumps and water-source units. The normally open configuration triggers a lockout or shutdown sequence if refrigerant pressure drops below the 35 PSI threshold, preventing the compressor from running in a vacuum. Rated for a functional range between 35-60 PSI, this high-durability sensor is built to withstand the rigorous cycling of commercial and residential geothermal systems. Integrating this ClimateMaster HVAC part into your maintenance workflow guarantees consistent performance and protects expensive equipment from overheating and mechanical seize-ups caused by low refrigerant levels.

Key Benefits

• Ensures accurate low pressure monitoring with a calibrated 35 PSI cut-out and 60 PSI reset range.
• Critical compressor protection against low refrigerant charge, preventing liquid slugging and motor burnout.
• OEM compatibility ensures seamless fitment and electrical alignment with existing ClimateMaster control boards.
• Durable brass body construction provides resistance to corrosion and vibration in demanding HVACR environments.
• Simplified installation as a direct ClimateMaster 13B0055N01 swap for malfunctioning safety switches.

Common Questions

Is the 13B0055N01 a normally open or normally closed switch?
This part is a normally open pressure switch that closes upon reaching the required pressure threshold to complete the control circuit.

What happens if my low pressure switch resets frequently?
Frequent tripping usually indicates a significant leak, a restricted filter drier, or an expansion valve (TXV) failure. Check your refrigerant levels and evaporator airflow before replacing the sensor.

Can I use this switch for high-pressure side monitoring?
No, this component is specifically rated for low-side pressure ranges (35-60#). Using it on the high-pressure discharge line will result in immediate switch failure and lack of system protection.
