Tips
Because food is frozen at about -7℃, it may take about 24 hours for the food to freeze completely.
The degree of freezing or freezer burn may vary depending on the food type, cooking method, storage
arrangement (stacking, storage location), the amount of food, and the storage time.
Depending on how much sugar, salt, moisture, or fat the food contains, freezing may not be possible or
the food may harden when frozen (cannot be cut immediately with a kitchen knife).
Food that has already thawed once is unsuitable for soft freezing. The texture and quality cannot be guaranteed.

The noise gets louder suddenly
or the tone changes.
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.
A whistling sound is made after
closing a door.
This is the sound of the cooling fan motor starting.
A whipping or dripping sound is
sometimes heard from inside the
refrigerator after a door is opened.
This is the creaking sound as warm air enters and
expands the plastic.
Sometimes the sound of flowing or
boiling water can be heard.
This is the sound of the refrigerant (gas) flowing.
Sound
A rattling or squeaking sound is made
sometimes (every 1 to 2 hours).
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.
After turning on the power, a thumping
or creaking sound may be heard in
the ice making “ICE STOP” mode
(every 1 to 2 hours).
This is the sound of the operation check. The check is
performed even in the “ICE STOP” ice making mode.
Problem Check Explanation and Action
Doors do not

Doors open
easily
Is a door making contact with food or a
case? Is too much food packed inside?
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.
Has food fallen behind a case in a drawer
door, or is the power cord or another object
trapped between the refrigerator and a door?
Remove any objects. Make sure that the door does not
trap objects such as food, power cords or plastic bags.
Is the refrigerator installed stably?
Are the adjustable supports making
contact with the floor?
Lower the adjustable supports to raise the front side
slightly and make the doors easier to close.
The alarm

When you hear noise from the lower rear of the refrigerator
Part of the cooling system is the compressor, which operating, does create a more noticeable increase in noise level.
This is normal. However, if the noise is quite loud, this could be because the refrigerator is not installed correctly on
a hard level surface, or there may be a problem that may need service.
