ClimateMaster High Pressure Switch

The ClimateMaster High Pressure Switch is a genuine OEM replacement safety cutout (high pressure cutout switch) for ClimateMaster water-source and geothermal heat pump equipment. It monitors refrigerant pressure on the discharge side of the system. If pressure climbs too high, it opens the control circuit to shut the system down.

Key Features:

• Protects the compressor from running against excessive head pressure
• Pressure-activated safety switch that opens the control circuit at its rated cut-out pressure and recloses at its lower reset pressure
• Wilspec-built OEM design made to ClimateMaster specifications
• Compact switch body for straightforward replacement
• Helps keep the heat pump running reliably and efficiently

A tripped high pressure switch usually points to an underlying problem, such as restricted water flow or abnormal system pressures. Technicians typically check these conditions before replacing the switch. Cut-out and reset pressure ratings differ between part numbers in this line, so pick the variant that matches your original switch.
