DEFROSTING THE EVAPORATOR
The following 2 types of defrosting methods is provided for the refrigerator. Both of them are controlled
automatically.
 Cycle defrosting
The refrigerator temperature is kept stable by ON/OFF operation of the compressor. When the
compressor is OFF (stopped), the frost on the evaporator is melted by the heater. This defrosting never
influences to the refrigerator temperature.
 Defrosting by defrost sensor
The cycle defrosting may not be sufficient to remove the frost on the evaporator when the ambient
temperature is high, the door is opened frequently, or heavy moist items are stored in the refrigerator. In
this case, the defrosting operation is started automatically when the defrost sensor detects the frost.
During the defrosting, dF is displayed on the temperature display.
After completion of defrosting, dF display is disappeared and the refrigerator returns to the normal
operation.
<Important>
During the defrosting, the refrigerator temperature reaches around 10 o C temporary.
<Reference>
Too much frost is accumulated on the evaporator when the refrigerator is running under high temperature
and humidity condition. For example, the defrosting operation is started once a week when the
refrigerator is running with 2
o
C setting at 35

C, 80 %R.H.
