TROUBLESHOOTING
Compare the room temp.
with sensed temp. using
Temp-Resistance Table.
When there is sensor error, display panel show that. When it occurs during the initial power on time,
display panel keeps blinking relevant 7-SEG and the refrigerator go into the emergency operation mode.
Under the emergency operation mode, the refrigerator can not do its normal operation. So check out
