Abstract

Apparatus for controlling a defrosting system in a refrigerator including temperature sensing devices to monitor the temperature of the evaporator coil and the storage space. When the difference in these temperatures exceeds a predetermined value, and one of the monitored temperatures is less than a predetermined value, the defrost operation will be initiated.
