INTEGRATED SERIES (DRAWERS) INTEGRATED SERIES (DRAWERS) Monitor and Control Refrigerator Fan-Assisted, Off-Cycle Defrost (All-Refrigerator Units Only) Temperature signals from the refrigerator compartment and evaporator thermistor’s are observed by the micro- processor. During the off cycle defrost, if the refrigerator compartment temperature reaches high offset (calling for cooling) before the evaporator temperature rises to 38-44°F (3-7°C), no power will be supplied to the compressor, but the evaporator fan will be switched ON.
