Check
Check the installation around the water tank. If there are
gaps, the cold air may escape and water may freeze.
Ice stored inside the ice storage box for a long time may
shrink or join together (due to a phenomenon called
sublimation).
When not using ice, it is recommended that you remove the
water and stop the ice making.
As the water in the water tank decreases, the amount of
supply water is slightly reduced.
Leave space around the refrigerator. When objects or walls are in
contact with the refrigerator, sounds may be heard.
Push in the water tank until it touches the rear side. If it is out of
position, the sound of the water supply pipe can grow loud.
If there are any gaps or looseness, the water may freeze,
causing sounds to be heard.
Immediately after beginning use, when the weather is hot,
when the doors are frequently opened and closed, and in
similar situations, the refrigerator switches to high-speed
operation and cools with high power.
This is the creaking sound as warm air enters and expands
the plastic.
This is the sound of the refrigerant (gas) fl owing.
This is the sound of the automatic ice maker. Even when there
is no water in the water tank, the automatic ice maker and pump
make a sound about every 100 minutes.
This is the sound of the operation check. The check is
performed even in the "ICE STOP" ice making mode.
Store food so that the door does not make contact with the
food when closed. In the refrigerator compartment, store
food on the shelves and in the drawer doors store food so
that it does not make contact with the ceiling when doors
are shut and opened.
Remove any objects. Make sure that the door does not trap
objects such as food, power cords or plastic bags.
Lower the adjustable supports to raise the front side slightly
and make the doors easier to close.
Refer to "When the door alarm sounds" and "When the
alarm cannot be turned off".
