5 Trouble shooting
Before calling for service, please read the following troubleshooting table first. This can save both your time and money. The
table contains common problems except those caused by defects in workmanship or material of the refrigerator.

The
compressor
does not work
The refrigerator is in the
defrosting cycle.
The refrigerator is not plugged into a
power outlet.
This is normal for an automatic
defrosting refrigerator.
Verify the plug is plugged in the socket
firmly.
The refrigerator
runs frequently
or runs for too

The indoor or outdoor
temperature is high.
The refrigerator has been powered
off for a period of time.
The door is opened too frequently or

The door of the fridge/freezer storage
compartment is not tightly closed.
The temperature setting is too low.
The door gasket of the
fridge/freezer storage compartment
is dirty, worn, cracked or
mismatched.
In this case, it is normal for the refrigera
t
or
to run longer.
Normally, it takes 8 to 12 hours for the
refrigerator to totally cool down.
Warm air enters the refrigerator and causes
it to start frequently. Please do not open the
door too frequently.
Ensure the refrigerator is
located on a level ground and there is no
food or container jarring the door. See
“door/drawer opening/closing” in section
“Problem”
Set the temperature higher until a
satisfactory refrigerator temperature is
obtained. It takes 24 hours for the
refrigerator temperature to become stable.
Clean or replace the door gasket. A
leakage gap of door gasket can cause a
longer running time of the refrigerator in
order to maintain desired temperature.
