ClimateMaster 69798801 High Pressure Switch

The ClimateMaster 69798801 High-pressure switch is used as a safety part in heating and cooling equipment especially water-source heat pump and geothermal systems. This switch measures the pressure of the refrigerant within the system. When the pressure reaches the upper safety level, the switch turns off the electrical circuit breaking the operation of the compressor. This helps avoid compressor or other system damage by high pressures that can result from, for example, overcharge of refrigerant, reduced airflow, or fouled condenser coils. As a result of avoiding possible expensive repairs and system lockage, the 69798801 guarantees proper and safe functioning of the HVAC.
