Annoying sound is
generated by the
refrigerator.
Does the floor bend?
Install a sturdy board with a thickness of 1 cm and then install the
refrigerator.
Pg.44
Does the refrigerator come in contact with the wall or furniture, etc.?
Install the refrigerator with clearance around it.
Is the refrigerator cooled down enough?
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.
Isn't “Sensor Cool” , “Quick Freeze” , “Spot Cool” and “Quick” set?
When it is set to “Sensor Cool” , “Quick Freeze” , “Spot Cool” and “Quick”,
operation sound of the compressor or the fan motor gets louder because of
high-speed revolution.
Operation sound lasts long.
−−−−−
As the compressor operates slowly for energy savings, you may hear an
operating noise for a long time.
Operation sound sometimes
becomes louder.
−−−−−
The operating power varies in response to changes in the inside
temperature of the refrigerator, and thus you may sometimes hear a
large noise.
When other sounds such
as shown in the right
table are generated by the
refrigerator.
Sound like water flowing (trickling)
Sound like collision (tapping)
Sound like water boiling (bubbling up)
Sound like meat roasting (sizzling)
These sounds are caused when the refrigerant flows or water flows/
evaporates to remove frost.
This is not malfunction.
Sound like squeaking (cracking) (knocking)
This sound is heard when the parts squeaks due to changes in temperature
in the refrigerator or atmospheric pressure in the Vacuum Compartment.
This is not malfunction.
Sound like something is caught (clacking)
Sound like roaring (honking)
Sound caused immediately after closing the door (booming)
These sounds are caused when the electric parts to control
the refrigerator temperature operates.
This is not malfunction.
Sounds caused by the Automatic ice maker
(zooming)
(rattling)
(clunking)
These sounds are made when ice is separated from the ice tray of the
auto ice maker or water is supplied to the ice tray.
This is not malfunction.
To stop the sound, touch the
button to change it to “Off”.

Door is not in a horizontal
state.
Is the installation site level?
This does not affect the refrigerator performance. Adjust the refrigerator
adjustable mount to keep it level if you want to correct it.
Pg.44
Does the soft floor material sink in around the legs due to the weight of
stored items?
Lay a firm board which has more than 1cm thickness on the floor if the
refrigerator itself inclines.

The side of the refrigerator
becomes hot. Hot air comes from
the bottom of the refrigerator.
−−−−−
Hot air may come from the bottom of the refrigerator to exhaust the heat
generated when the cooling device operates.
The temperature may rise to 50 – 60 ˚C immediately after installation or
during summer.
It does not pose safety or performance problems, but avoid touching it.

Hissing sound does not
occur when opening.
Is the setting of the Vacuum Compartment to “Off (Non-vacuum)?
Change the setting to “-1˚C (Subzero)” or “+1˚C (Chiller)”.
Pg.51
Is the handle pulled up?
Hold down the handle to lock.
Is the handle held down to the end and locked?
The vacuum function will not work unless it is locked.
Press the handle until it stops to lock it.
Isn’t the Vacuum Compartment Gasket removed?
Install the Vacuum Compartment Gasket.
Pg.63
Is there anything that is caught stuck to
the gasket of the vacuum compartment
or its retainer? Is the gasket or its
retainer dirty?
Remove any packaging material of foods or other things which are caught in.
If the gasket is dirty, clean it.
Pg.63
Is there any stuck parts on gaskets?
If a part of the gasket is stuck together, the vacuum ompartment
will not be able to maintain a vacuum state.
If there is a part stuck together, peel such part off.
Since it is difficult to see the left and right side faces and
the bottom, such part shall be confirmed with removing the
vacuum compartment.
Pg.66
If the gasket is dirty, clean it.
Pg.63
If it is damaged or deformed, replace it.
Pg.73
Was the door of the Vacuum Compartment or the Refrigerator
Compartment opened / closed just before?
It takes about three to four minutes for the Vacuum Case to be vacuumed
after the vacuum pump starts to operate. Wait for more than four minutes
after opening or closing.
