● 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.

・  Sound like water fl owing (trickling)

・  Sound like collision (tapping)

・  Sound like water boiling (bubbling up)

・  Sound like meat roasting (sizzling)

・  Sound like squeaking (cracking)

・  Sound occurred sometimes (clacking)

・  Sound like something is caught (clacking)

・  Sound like roaring (honking)

・  Sound caused immediately after closing the 

door (booming)

・  Sounds caused by the Automatic ice maker

 (zooming)
 (rattling)
 (clunking)

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.

This sound is caused when the refrigerator starts the operation to cool.

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 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.

● 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.

● Refrigerator may not be installed properly.

Floor bends

Leg cover comes off

Refrigerator comes in contact 
with the wall or furniture, etc.

Lay the fi rm board on the fl oor and install the refrigerator on it.

Allow clearance around the refrigerator and install it.

● 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.
