Failure analysis
The following items shall be inspected before occurring failures which require maintenance:
Failures:Refrigerator does not work,The refrigeration effect is poor
Causes:1. Check the connection of power supply. 2. Check whether the refrigerator is exposed to
direct sunlight or whether there is heat source nearby. 3. make sure the minimum
recommended space is around the fridge and wall.
Failures:Foods in refrigerating chamber are frozen
Causes:1.
Check whether the setting temperature is too low, you may need to increase. 2. Check
whether foods with too much water are too close to the rear wall and move if required.
Failures:
There are abnormal sounds in the refrigerator
Causes:1.
Check whether the bottom of refrigerator is stable, re-level if required. 2. Check whether the
refrigerator is too close to the wall and move if necessary. 3. Check whether the refrigerator touches
other objects and remove any obsticles.
Failures:
There is an abnormal odor in the refrigerator
Causes:1.
Check whether the foods are sealed for storage. 2. Check whether the refrigerator is clean, and
clean as described in this manual 3. Make sure food has not been stored for too long, and discard if
required.
Non-failures
Phenomenon:The two sides of the refrigerator, and space between the fridge and freezer
are warm
Cause:Refrigerator pipes (condenser, anti-fog pipes are on two sides and front part of refrigerator
for heat dissipation and to prevent condensation, it is normal for these spaces to get warm
Phenomenon:The door is too tight and not easy to open
Cause:Reopening of the door immediately after closing it is hard because hot air enters the
refrigerator and contracts to produce a pressure difference. It will be easy to open the door after a
Phenomenon:There is water ripple noise in refrigerator
Cause:When starting or stopping the compressor, the refrigerant will make such a
sound;and;Water produced after defrosting will also make such sound.
Phenomenon:There is “Click” sound or tick sound in refrigerator
Cause:Shrinkage and swelling of the case will make such sound;When the case is cold or the
door is opened, this sound will occur;
Cause:Running of compressor will make such a sound (if the refrigerator is not leveled, this sound
will be louder
Phenomenon:There is condensation or frosting on the freezer door surface or food
surfaces
Cause:Temperature or humidity around the refrigerator is high;The door is opened for too
long ;Food with too much water are not sealed or tightly wrapped.
Phenomenon:There is condensation on the light covers
Cause:Light will produce heat after being lit, if the door is opened for a long time. So there is
temperature difference, and thus the light cover will have condensation.
Phenomenon:There is condensation and water mist on the refrigerator body
Cause:Humidity around refrigerator is high, and the moisture in the air will gather on the cabinet
to form condensation.
