The True 800360 thermostat by Therm-O-Disc (37T21) is a cutoff switch that shuts down the defroster in your freezer when it reaches a certain temperature, known as the actuation point. The switch works by reacting to the temperature of the defrost coil heater and opening the circuit so that the heater no longer receives power. Without a properly working defrost cutout switch, your defrost heater will not work properly and can negatively affect the overall operation of your freezer. The True 800360 defrost cutoff switch by Therm-O-Disc (37T21) works with a number of True freezers.
