safety cutout on the refrigerant discharge side of ClimateMaster water-source and geothermal
heat pump equipment. It is a Wilspec-built switch rated 600/450 PSI and wired normally closed.

About this part

A high pressure switch protects the compressor from running against excessive head pressure.
When the switch trips, it usually points to a real underlying problem rather than a faulty
switch. Common causes include a dirty or blocked condenser coil, low water flow or a fouled heat
exchanger on a water-source unit, an overcharge of refrigerant, or non-condensables in the
system. For that reason, technicians normally verify pressures and water flow before replacing
the switch itself.

Because ClimateMaster used several pressure switches across its product lines, check the part
number stamped on the switch body or listed on your unit’s parts breakdown before ordering. If
you are unsure, send us your model and serial number and we will confirm the correct part.
