Description
The Rheem-Ruud 42-102056-06K Dual Pressure Switch is a refrigerant control used to monitor both high-pressure and low-pressure conditions within heating and cooling equipment. In HVAC systems, it is installed in heat pumps and air conditioning units where it helps protect compressors and refrigerant circuits from operating outside safe pressure ranges. It responds to abnormal pressure fluctuations by interrupting the control circuit when limits are exceeded and restoring operation once conditions return to normal. It helps in maintaining refrigerant system protection, operational stability, and performance in residential and light commercial heating and cooling applications.
