TROUBLE DIAGNOSIS
4-2. Measures for Symptoms on Temperature
Problems
Refrigeration is weak.
The food in the chilled drawer is
not frozen but defrosted.
Refrigerator water is not cool.
Ice cream softens.
Refrigeration is too strong.
Vegetables are frozen.
The food stored at inside of
the shelf freezes even the
control button is set at MID.
I Check temperature set in the temperature control knob.
• Refrigerator is generally delivered with the button set at normal use (MID).
But customer can adjust the temperature set depending on their habit and taste.
If you feel the refrigeration is weak, then set the temperature control button at
strong position. If you adjust the button in the freezer compartment as well,
the refrigeration is stronger than adjusting refrigerator only.
I The chilled drawer does not freeze food.
• Use chilled drawer for storing fresh meat or fish for short periods. For storing for
a long periods or freezing food, use a freezer compartment. It is normal that
frozen foods thaw above the freezing temperature (in the chilled drawer).
I Check the water storage location.
• If water is kept in the door rack, move it to a refrigerator shelf. It will then
become cooler.
I Explain the characteristics of ice cream.
• The freezing point of ice cream is below -15°C (5°F). Therefore ice cream may
melt if it is stored in the door rack.
• Store ice cream in a cold place or set the temperature control button of a freezer
at strong position.
I Check the position of temperature control button.
• Check if refrigeration is strong in whole area of the refrigerator or partly near the
outlet of the cooling air. If it is strong in whole area, set the control button at
weak. If it is strong only near the outlet of cool air, keep food (especially damp
foods and easily frozen foods) away from the outlet.
I Check the vegetables storage.
• If vegetables are stored in the refrigerator shelf or chilled drawer instead of
vegetable drawer, they will be frozen. Set the control button at weak if they are
also frozen in the vegetable drawer.
I Check if food is stored near the outlet of the cooling air.
• The temperature at cooling air outlet is always below the freezing point.
Do not store food near the outlet of the cooling air as it block the air circulation.
Do not block the outlet. If the outlet of the cooling air is blocked, the refrigerator
compartment will not be cooled.
