Troubleshooting
This is not a malfunction of the refrigerator.
The surface of the
refrigerator is hot.
If a door is shut,
other doors may open.
Does the refrigerator make any
abnormal noises (sound)?
● The refrigerator is equipped with the dew prevention and heat radiation tubes.
The back and side plates may be heated especially when starting up or if the door is frequently opened and closed.
● The two compartments are connected with an air duct. When closing one of the doors, the door may be opened by
the air pressure through the duct. This is a normal phenomenon.
● The sound like water flowing and boiling water is the sound of the cooling liquid (refrigerant).
There are waving and/or distortions
on the door surface, the side and
the top surface of the refrigerator.
● Slight waving and/or distortions are generated in the manufacturing process of the refrigerator.
They may be conspicuous according to the position of the light source and/or the brightness etc.,
but there is no problem with the performance.
● A creaking sound comes from the storage compartment. It is the sound caused by friction of the parts due to temperature change
.
Before you call for service, please check the following items:
The refrigerator does not get cold at all.
The refrigerator does

Annoying sound is generated
by the refrigerator
●
You may feel that the operation sound is larger because the compressor operates in high-speed under the following conditions : the
refrigerator does not cool fully on the occasion such as using it for the first time, opening/closing the door frequently, the surrounding
temperature is high.
The sound becomes small after cooling fully.
The compressor operates at low speed at night, for long vacations or absences, potentially developing large vibrations.
Operation sound lasts long.
It is because the compressor operates in low-speed for conserving energy. ●
Operation sound sometimes
becomes larger.
● It is because the system changes the operating power of the refrigerator according to the temperature change.
