Failure Analysis; Non-Failure - TCL RT210WM2110 Mode D'emploi

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. Check whether there is heat
dissipation space around refrigerator.
Remedies: 1. Connect the power supply. 2. Move the refrigerator to a place without direct
sunlight and heat source. 3. Leave sufficient space between refrigerator and wall.
Failures: Foods in refrigerating chamber are frozen
Causes: 1. Check whether the setting temperature is too low. 2. Check whether foods with too
much water are too close to the rear wall.
Remedies: 1. Adequately increase the temperature. 2. Move the foods with too much water to
the door side of glass shelf.
Failures: There is abnormal sound in refrigerator
Causes: 1. Check whether the bottom of refrigerator is stable. 2. Check whether the refrigerator
is too close to the wall. 3. Check whether the refrigerator touches other objects.
Remedies: 1. Adjust the bottom adjusting leg to stabilize the refrigerator. 2. Leave sufficient
space around refrigerator. 3. Remove the obstacles.
Failures: There is abnormal odor in refrigerator
Causes: 1. Check whether the foods are sealed for storage. 2. Check whether the refrigerator is
clean. 3. Check whether the foods are stored for too long time.
Remedies: 1. Sealed foods for storage. 2. Regularly clean the refrigerator. 3. Do not store foods
for too long time.
Non-failures
Phenomenon: Fever or hot on two sides and spacing part surface between refrigerating
chamber and freezing chamber.
Cause: Refrigerator pipes (condenser, anti-fog pipes) are on two sides and front part of
refrigerator for heat dissipation and to prevent from condensation.
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 pressure difference. It is easy to open the door after a
while.
Phenomenon: There is water ripple in refrigerator
Cause: When starting or stopping the compressor, the refrigerant will make such sound;
Water produced after defrosting will also make such sound.
Phenomenon: There is "Click" sound or tick sound in refrigerator
Cause: Shrinkage and swelling of case will make such sound; When the case is cold or the
door is opened, this sound will occur; Phenomenon: There is hum sound in refrigerator
Cause: Running of compressor will make such sound (if the refrigerator is not leveled, this
sound will be louder)
Phenomenon: There is condensation or frosting freezing chamber door surface or food
surface
Cause: Temperature or humidity around the refrigerator is high; The door is opened for too
long time; The foods with too much water are not sealed or tightly wrapped
Phenomenon: There is condensation on the built-in light surface
Cause: Light will produce heat after being lit, and the door is opened for too long time. So
there is temperature difference, and thus the light case will have condensation.
Phenomenon: There is condensation and water mist on body
Cause: Humidity around refrigerator is high, and the moisture in the air will gather in the case
to form condensation
