Operation sound lasts long.

Annoying sound is generated
by the refrigerator.
● You may feel that the operation sound is loud 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 more quiet after cooling fully.
The compressor operates at low speed at night, or during
long vacations or absence.
If a door is shut, other doors
may open.
●
The two compartments are connected with an air duct.
When closing one of the doors, the other door may be
opened by the air pressure through the duct.
This is a normal phenomenon.
Does the refrigerator make any
abnormal noises (sound)?
● The sound like water flowing and boiling water is the
sound of the cooling liquid (refrigerant).
● A creaking sound comes from the storage
compartment. It is the sound caused by friction of
the parts due to temperature change.
-
There are waving and / or
distortions on the door surface,
the side and the top surface of
● 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.
The door of the freezer
compartment was not left
open temporarily?
Check that the wrapping paper of the food is not getting
caught in order not to make gap between door and
door gasket when you close the door.
When the door is opened frequently or if the door
is opened when the humidity around the refrigerator
is high, moisture in the air may be turned into some
frost or ice on the inner wall or component of the
freezer compartment, or around the air chanels.
This is not a failure. Please try not to open the door
too many times or for a long time. Also, please wipe
frost or ice generated in the freezer compartment off
The door of the freezer
compartment was not
opened frequently or longer
time than necessary?
Making extra ice by using
an additional ice-tray which
was not originally installed
in the refrigerator?
When the many containers in which water or liquid is stored
are put in the same time, water or liquid may be evaporated
and turned into frost or ice on the wall or component of the
freezer compartment, or around the air channels. You can
suppress these frost and ice by putting lid to avoid evaporation
Please wipe frost and ice off with use of a dry cloth.
Frost or ice is generated in
the freezer compartment
with use of a dry cloth.
Dew or Frost is generated
the refrigerator.
Possible causes and / or Recommened solutions Please check here General operation
It is because the compressor operates in low-speed for
conserving energy
It is because the system changes the operating power of
the refrigerator according to the temperature change.
Operation sound sometimes
becomes louder.
This is not a malfunction of the refrigerator:
