The True 800316 Defrost Termination Switch (37T23) controls the defrost heating elements on a True freezer. During the defrost cycle, the 37T23 controls the heat of the evaporator coils. When the set temperature is reached the switch shuts down the power to the heating element. This means the coils get warm enough to melt the ice build up, but not warm enough to significantly warm the freezer compartment. The 37T23 is a three-wire defrost termination switch with a make and breakpoint of L55 and a differential of 15F. The True 800316 (37T23) is the correct replacement for a variety of GDM, T,TA, TG, and TS freezers.
