The Supco SLT45 Refrigerator Defrost Thermostat 37T31 Style 611454 can be attached to the evaporation coil to detect when the amount of frost in the appliance has accumulated to a specific level that requires it to defrost. It switches off or on the heater depending on the level of coil temperature to enable the system to melt the ice without excessive heating of the compartment. It is installed in the evaporator space, and functions as a part of the automatic defrost system, keeping airflow passages open.
