Monitor and Control Refrigerator “Fan-Assisted, Off-Cycle Defrost”

Temperature signals from refrigerator evaporator's thermistor’s are observed by the microprocessor. During off cycle
defrost, if a refrigerator zone temperature reaches high offset (calling for cooling) before evaporator temperature
rises to 38°F (3°C), no power will be supplied the the compressor. But, the the zone evaporator fan will switch ON.
Once the evaporator temperature reaches 38°F (3°C), normal cooling functions begin. (See Figure 3-23).

NOTE:

If refrigerator compartment thermistor is faulty, compressor operation defaults to 20 minutes ON, 40 minutes

OFF cycling, EE appears in left of LCD, SERVICE will flash and Error Code 05 will be logged.

NOTE:

If evaporator thermistor is faulty, the compressor will not energize until zone air temperature exceeds high

offset by 5°F (3°C). SERVICE flashes and Error Code 06 is logged.

NOTE:

When in Sabbath

Mode, the refrigerator com-
partment thermistor still con-
trols compressor operation,
except there is a random 15
to 25 second delay before
the compressor is energized.
