Description
Part
4 Defrost Compressor
Function F-fan
C-fan
5 Defrost Compressor
Function F-fan
C-fan
1. During defrost function, comp. goes off and F-fan goes ON.
2. Maximum defrost time is 70 minutes.
3. Defrost function is controlled by time interval setting.
4. Time interval can be set by shifting dip s/w on the PCB.
5. Time interval setting is as follows.
Dip Switch Cycle time
No.1 No.2 (hours)
00 60
10 48
01 36
11 24
6. Factory setting is 24 hours
7. The first defrost function will start at the half value of setting time.
1. If it becomes defrost cycle time, the refrigerator executes defrost function.
2. Defrost method is to operate only F-fan with comp. off.
3. Defrost function terminates when D-sensor temperature comes to above
50.0˚F(10˚C).
4. During defrost period, LED on the PCB does not display ‘dF’ but inside
temperature, in difference to “Freezer Model”. But, if inside temperature is
above 39.2˚F(4˚C) during defrost period, LED displays 39.2˚F(actually ‘39’),
imaginarilly.
5. After defrost completed, if inside temperature comes to go down below
39.2˚F(4˚C), LED displays real time temperature.
