The SUPCO gls70 is a Gemline series defrost thermostat designed to regulate the defrost cycle in refrigeration equipment. It monitors evaporator coil temperature and opens the defrost circuit once the set termination temperature is reached, preventing over-defrost and protecting system components. This thermostat is a direct-mount, low-mass component suited for installation in commercial and residential refrigeration units. Licensed refrigeration technicians and appliance service professionals are the typical installers for this part.
The gls70 is used in refrigeration systems where automatic defrost cycle control is required. It mounts directly on or near the evaporator coil and terminates the defrost heater circuit at the appropriate temperature. Typical applications include reach-in coolers, walk-in units, and domestic refrigerator-freezer combinations where a reliable defrost termination device is needed.
Designed as an OEM-style replacement defrost thermostat for residential and light commercial refrigeration systems requiring evaporator coil defrost cycle termination.
Installation should be performed by a qualified appliance or refrigeration technician. Disconnect power to the refrigeration unit before accessing the evaporator compartment or handling any electrical components. Secure the thermostat body against the evaporator coil surface according to the equipment manufacturer's mounting instructions. Verify the replacement thermostat termination temperature matches the original specification before returning the unit to service.
