ClimateMaster 13B0015N05 Pressure Switch

The ClimateMaster 13B0015N05 Pressure Switch is a critical safety component designed for high-pressure monitoring in geothermal heat pumps and water source heat pump (WSHP) systems. This OEM high pressure switch is calibrated with a precise 400 PSI cut-out and a 50 PSI cut-in reset point, ensuring robust compressor protection against excessive discharge pressures. Built to handle the rigorous demands of industrial and commercial HVACR environments, this switch integrates directly into the refrigerant safety circuit, typically wired in series with the compressor contactor coil to trigger an immediate shutdown when setpoints are exceeded. This mechanism is essential for preventing catastrophic component failure during high pressure lockout events, often indicated by a Code 2 fault on DXM or CXM control boards. Whether you are performing a routine service or a major HVAC repair, using this genuine 13B0015N05 replacement part ensures the system maintains its original engineering specifications for safety and efficiency.

• Precise Pressure Regulation: Features a factory-set 400/50 PSI threshold to prevent equipment damage from over-pressurization.
• Enhanced System Reliability: Actively monitors refrigerant levels to maintain safe operating parameters and extend compressor life.
• OEM Compatibility: Designed specifically for ClimateMaster Tranquility series and compatible Carrier HVAC units.
• Direct Safety Integration: Facilitates immediate system lockout via the control board to protect the liquid and discharge lines.
• Durable Construction: Engineered for industrial-grade longevity in demanding geothermal and water-source applications.

• What causes a High Pressure lockout (Code 2) on a ClimateMaster unit? This is usually triggered by the 13B0015N05 switch due to restricted water flow, an overcharged refrigerant system, or a fouled heat exchanger.
• Can this pressure switch be used with R-410A systems? Yes, the 400 PSI cut-out is standard for protecting components in modern high-pressure refrigerant cycles.
• Is the reset manual or automatic? This switch is designed to reset at 50 PSI; however, the control board typically requires a soft or hard reset to clear the lockout code.
