Noise bothers me
A bubbling or clicking
sound is heard when
the door is closed.
The top of the
refrigerator is hot
Front (or side) panel
is hot
The control panel does
not work.
When a door is closed,
another door is opened.
The door is heavy when
opening it immediately
after closing.
●
Is the floor tough and horizontal? (P. 6)
●
Do both the legs reach the floor and is the refrigerator properly fixed? (P. 6)
●
Do the sides of the refrigerator not touch the walls or furniture
around the refrigerator? (P. 6)
●
Does the power cord of the refrigerator not touch the walls or furniture
around the refrigerator? (P. 6)
●
The compressor or the fan may make loud noise when the refrigerator
is being cooled, such as when the refrigerator is not still cooled soon
after installation; the doors are frequently opened and closed; the temperature
around the refrigerator is high, or quick freeze is set ON. This is not abnormal.
→
When the refrigerator has been cooled, the noise becomes small.
●
Air taken into the interior is suddenly cooled. The inner pressure becomes
lower than the external air momentarily. The items in the compartments seem
to have been “sucked”.
●
When the door is closed with a force or the floor is uneven, the refrigerator
shakes and generates noise. Place a plate under the refrigerator to prevent
it from shaking. (P. 6)
●
The left and right side surfaces may become hot to let out heat generated
when the refrigeration system operates. The temperature may become
50
℃
to 60
℃
(when the ambient temperature is 30
℃
) after installation
or in the summer, but this is not abnormal.
●
Are you operating a control panel with the PC door opened?
●
Is the operation lock set?
→
If “CL” is displayed on the notice indicator area during operation,
disable the operation lock. (P. 20
）
●
Wind pressure by closing a door may open another door for an instant.
●
Air taken into the interior is suddenly cooled. The inner pressure becomes
lower than the external air momentarily. The doors seem to be pulled
towards inside.
●
The mechanical section releases heat. (P. 6

●
When you use this refrigerator for the first time, ice will be made
after the interior has cooled down sufficiently.
(24 hours or more may be required.)
●
Is the ice making function set to “AUTO ICE OFF” ?
(Is the
「
AUTO ICE OFF
」
display not turned off? )
（

）
●
Are the water supply tank (P. 12) and ice-making tray (P. 15) set correctly?
●
Is there any food etc. in the ice storage box?
●
Do you not frequently take in and out the ice-making tray?
●
To confirm whether the icemaker is operating, press the button first,
press the button until
「
AUTO ICE OFF
」
flashes, then press
the button for at least 10 seconds.
If the water in the water supply tank decreases, the icemaker is operating.
(If water has spilled into the storage case, wipe it off.)
Ice cubes are not
frozen inside
●
Has the freezer compartment temperature control been set to “ 1 ” ?
→
Set it to “ 2 ” or “ 3 ”. (P. 9)
The shape of ice is not
“cubic”
●
There are projections.
→
They are the connecting parts frozen in the ice-making tray.
●
The ice cubes are round or connected to other ice cubes.
→
Isn’t the ice stored for a long time?
(Ice cubes get round or connected by sublimation.)
●
The ice is small.
→
Small ice cubes sometimes produced when water in the tank is exhausted.
Ice smells
●
Do you clean the water supply tank and purification filter once a week? (P. 15)
●
Is any cleaning agent, benzine, bleach used for caring?
（
P. 15
）
●
Is the water purification filter deteriorated? (P. 15)
●
Have you put strong smelling foods into the other compartments?
The interior smells
●
Are strong smelling foods hermetically sealed?
●
Odor often attaches to the interior walls.
→
Dip a soft cloth in lukewarm water and squeeze it. Wipe it with this cloth.
Does not get cold at all
●
Is it indicated in the “Notice” area of the control panel? (P. 17)
●
When you use this refrigerator for the first time, from 4 to 24 hours
or even more are required until the refrigerator begins to cool.
●
Has the power supply failed?
Does not get cold
enough
●
Is the temperature control set to “ 1 ” ?
→
Set to “ 2 ”. (P. 9)
●
Is a food item blocking the cold air outlet? (P. 7)
●
Is the refrigerator subject to direct sunlight or are there any heating
devices in its vicinity? (P. 6)
●
Is sufficient spaces secured around the refrigerator? (P. 6)
●
Is a hot item stored, doors opened frequently, or too much food stored?
●
Is the front grille covered with dust? (P. 6)
Frost and dew
Freezer compartment/refrigerator compartment
●
This condition occurs when humidity is high, door was kept open for a
long time, or opened frequently.
●
Is a door slightly open due to a commercially available tube stand or the like
being caught in it or too much food being put in the refrigerator?
Vegetable compartment
●
Because the humidity in the vegetable compartment has been set higher.
Outside of the refrigerator
●
May occur when using
「
QUICK FREEZING
」
in succession when there is high humidity.
→
Simply wipe with a piece of dry cloth.
The food is frozen
●
Has the temperature control been set to “ 3 ” ?
→
Set it to “ 2 ”. (P. 9)
●
Is the ambient temperature 5
℃
or below?
→
Set it to “ 1 ”. (P. 9)
●
Did you put food with high water content near the cold air outlet in the
refrigerator (P. 7) or in the chilled room?
If you feel that the refrigerator is not working properly, check out the following points first.
If the trouble persists, disconnect the power plug and contact your dealer or an authorized service center.
The following sounds are not abnormal.
This section explains by using the
illustration of NR-C370EH.
From inside the refrigerator
• Snapping sound
The sound of parts expanding and
contracting as a result of temperature
changes.
• Zooming sound
The sound of the fan operating.
From the back
• Bubbling, hissing, and flowing
sounds
The sounds of refrigerant (gas)
flowing.
From the bottom of the back
• Clicking sound

• Hissing sound
The sound of water being evaporated
by the heater during defrosting.
From the automatic icemaker and
water supply tank
• Whirring, rattling, and bubbling sounds
The sounds produced when ice is released
by the automatic icemaker and water is
supplied. (approx every 2 hours).
