Supco SL10068 Defrost Thermostat L140-30F

The Supco SL10068 Defrost Thermostat is a temperature-sensing component used to control defrost operation in refrigeration and cooling equipment. It monitors evaporator coil conditions and activates or stops the defrost heater cycle based on the detected thermal state in HVAC systems. It is set up in refrigerators, freezers, and heat pump systems where automatic frost removal is required. Positioned near the evaporator assembly, it regulates heater operation during defrost periods and allows the system to return to normal temperature control.
