Failure Analysis
Non-failure analysis
• Both sides of the refrigerator has a condenser, it is a normal phenomenon to have heat
dissipation during operation.
• The temperature is high inside the refrigerator during the first time operation, cooling time will
be longer.
• Due to the high flow rate of refrigerant in the capillary within the refrigeration system, water
running sounds may occur sometimes.
• When the humidity is high, it is a normal phenomenon to have dew appearing on the refrigerator
surface and particularly near the door sealing.
• Buzz: Buzz will be generated by running compressor specially when starting up or shutting
down.
• Clatter: The solenoid valve or electric switch valve will clatter which is a normal phenomenon and
does not affect the operation.
• The refrigerating chamber will periodically frost and defrost (water drops will be generated on the
backside of the refrigerating chamber when defrosting) which is normal.
• When closing one of the doors, the another one may be opened because of the air flow pressure,
which is normal.
Trouble Shooting
For following troubles, check the possible cause and solution before calling for services.
Problems
Refrigerator is not working
Cooling performance is not good
Food in fridge compartment is
frozen
Abnormal noise
Possible Cause & Solution
• Check if the power is connected; voltage is too low; power cord is
firmly plugged
• Check if food storage is overcrowded
• Check if there are too many cooked food stored
• Check if the door opens frequently or open the door for too long
• Check if dissipation space around the refrigerator is enough (Please
refer to Page 28)
• Check if the doors are shut properly or the door seal is damaged or
deformed
• Check if the placement too close to stoves or sunlight
• Check if fridge compartment temperature is set too low
• Check if a lot of food placed too close to the back wall, or food is too
moist
• Check if the floor is flat or the refrigerator is placed steadily
• Check if refrigerator touches the wall or other objects
• Check if all accessories are in right place
• Check if refrigeration pipelines inside compressor touch each other
• Bottles or containers fallen or rolling
