Possible Cause
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 fi rst time,
opening/closing the door frequently, the surrounding temperature is high.
The sound becomes soft after cooling fully.
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.
The following sounds are generated when the refrigerator is operating normally, so they do not
indicate any trouble.
Type of sound
Sound like water fl owing (trickling)
Sound like collision (tapping)
Sound like water boiling (bubbling up)
Sound like meat roasting (sizzling)

The refrigerator may be charged with static electricity, but there is no problem with the safety.
It is recommended to ground if you want to remove it.
It is caused by the electromagnetic radiation slightly generated from this refrigerator.
Install the refrigerator on a place far away from the television, radio and interphone etc.
It is recommended to connect the power plug to the power outlet separated from the antenna
terminal and ground the refrigerator.
Those lines are caused by the liquid resin fl owing when plastic is molded.
They are especially conspicuous for the transparent parts, but there is no problem with the
strength and they can never lead to any cracks.
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 displayed character will disappear about 2 minutes after the operation fi nishes. However, Quick
Cooling or eco operation indicator lamp will not be turned off. Push either button to turn it on.
This hole is used to escape the air inside when fi lling the heat insulation
material into the door during the production process. It is neither a fl aw nor
abnormal thing.
Please check. This is the cause.
Possible Solution
Lay the fi rm board on the fl oor and install the refrigerator on it.
Allow clearance around the refrigerator and install it.
Install it fi rmly. Pg.36
These sounds are caused when the refrigerant to cool the
refrigerator fl ows or water fl ows/evaporates to remove frost.
This sound is caused because the parts squeaks when the
refrigerator temperature changes.
These sounds are caused when the electric parts to control
the refrigerator temperature operates.
These sounds are caused when ice separates from the ice tray
of the Automatic ice maker or ice is supplied to the ice tray.
These sounds also occur every 2 hours if the water supply
container is empty.
If you turn off the OFF lamp, ice making stops and the
sound does not occur.
This sound is caused when the refrigerator starts the operation to cool.
