The True 831994 defrost timer (Grasslin DTSX-B-120-TM) is the heart of the defrost system of a True refrigerator or freezer. The automatic defrost system prevents ice from building up on the evaporator coils by regularly suspending the refrigeration cycle and turning on heaters to melt any ice that may have accumulated. When the coil is free of ice, the timer begins the refrigeration cycle again. The DTSX-B-120-TM has no enclosure and replaces the True 831913.
