Troubleshooting
When this happens Check Item How to solve/repair
Frost and/or dew occur
Frost and/or dew adhere 
to the refrigerator interior 
or the frame of the drawer 
compartment.
Was the door or the drawer not temporarily shut completely?
Check that any food or package caught in the door, and then close it completely.
The door may be opened/closed frequently or door may remain open for 
a long time.
Open or close the door quickly, or reduce frequency of opening and 
closing the door.
Frost or condensation may be formed when the warm air contacts with 
inside the compartment or the door frame.
Wipe it off with a dry cloth.
Frost or condensation is formed on the wall or any part of the freezer 
compartment due to the moisture in the air when the door is opened or closed. 
No trouble 
Wipe it off with a dry cloth.
Dew adheres to the outside 
of the refrigerator (exterior, 
door gaskets, door and 
drawer compartment etc).
Dew may adhere to those parts when the indoor humidity is high (ex: 
rainy day).
No trouble 
Wipe it off with a dry cloth.
When the dew-proof heater is set to low, high humidity may cause 
condensation on the iron partition, the door gasket or the door.
Cancel the settings of the condensation prevention heater. 
Wipe it off with a dry cloth.
Pg.55
When the temperature is set to “
■■■
”, it may cause condensation 
on the surface of the door.
Wipe it off with a dry cloth. 
Please set the temperature to “
■■
”.
Dew condensation 
occurs in the Refrigerator 
Compartment.
Condensation may form on the wall and/ 
or around the cold air blowout port when 
the door is opened and closed frequently 
or the humidity is high around the 
refrigerator.
No trouble 
Wipe it off with a dry cloth.
Dew condensation 
occurs in the Vegetable 
Compartment.
The humidity in the Vegetable Compartment, among others, space for aero-care 
zone is higher than in any other compartment. This is because it is necessary to 
ensure optimal freshness of vegetables, which is not a malfunction.
When it is undesirable that dew occurs, wrap food and then store.
Water may drop into cases placed in the Vegetable Compartment due to 
dew concentration.
Water may cause damage to food, so wipe off water with a soft cloth.
If the moisture unit is blocked by food bag or container, dew may be 
formed in the space for aero-care zone.
Move the food bag or container blocking the moisture unit to other 
locations.
Refrigerator 
cools overly

Food freeze.
“

Pg.45, 49
The surrounding temperature is lower than 5˚C.
When the ambient temperature is low, the inside of the refrigerator may 
cool overly. Switch the temperature setting to “
■
”.
Is it placed in front of the Cold Air Blowout Port? Do not place any food in front of the cold air blowout port.
Door is not in a 
horizontal state
Door is not in a horizontal 
state.
The installation site may not be level.
This does not affect the refrigerator performance. Adjust the refrigerator 
adjustable mount to keep it level if you want to correct it. 
Pg.42
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.
More force is required to 
open the door immediately 
after closing the door.
It is because the air that entered the Refrigerator Compartment is rapidly 
cooled and the pressure in the Refrigerator Compartment temporarily 
lowers.
This is not malfunction.
Another door opens after 
closing 1 door.
Another door may open for a moment by the wind pressure because cool 
air path connects each compartment.
This is not malfunction.
Abnormal operating sound is generated
Annoying sound is 
generated by the 
refrigerator.
Does the floor bend? Lay a firm board and then install the refrigerator thereon. 
Pg.42
Does the refrigerator come in contact with the wall or furniture, etc.? Install the refrigerator with clearance around it. 
Does the leg cover come off? Install it firmly.
Pg.42
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 soft after cooling fully. 
Vibration may get louder because the compressor will run at low speed 
when no food is taken in or out for a certain time such as at night or 
during absence from home. 
When it is set to “
Freezer
”/“
Fridge
”/“
Quick
”, operation sound of the 
compressor or the fan motor gets louder because of high-speed revolution.
This is not malfunction.
Operation sound lasts long.
It is because the compressor operates in low-speed for conserving energy.
This is not malfunction.
Operation sound sometimes 
becomes louder.
It is because the system changes the operating power of the refrigerator 
according to the temperature change.
This is not malfunction.
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 caused because the parts squeaks when the refrigerator 
temperature changes. 
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. These sounds are also 
heard every 2 or 3 hours when the water supply container is empty. 
This is not malfunction. 
To stop the sound, touch the
 button to change it to “
Off
”. 
Pg.51
Sound occurs sometimes (clacking) This sound is caused when the refrigerator starts the operation to cool.
