PART IX TROUBLESHOOTING GUIDE
TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE Solution
Refrigerator does not
operate
1. Not plugged in
2. The appliance is turned OFF
3. The circuit breaker tripped or a fuse has blown out
4. PCB faulty
Press ON/OFF
Check and make sure the power plug is well connected
Ask engineer for help
Refrigerator is not
cold enough; can not
cooling down to
preset temp.
Compressor does not start ask engineer for help, check the connection of compressor
Compressor self-protected and stop operating
Ambient temperature is too high and over 38C degree
Air venting is not smooth, check the air duct and make sure it is not blocked
Fan operates slowly or faulty and stop operating.
Door is not closed completely, or door open for long time
Compressor or its components faulty
Fans stop working or low speed operating
Ask engineer for help, power on the cooler, check the fan whether the voltage is normal or not. If
the voltage is not normal, it should be PCB or circuit faulty. If the voltage is normal, the fan
should be damage
Evaporator ice up
Turn OFF the cooler for one hour, sometimes need also open the door, ice on evaporator will
melt. Then turn ON and check again.
Door is not well closed
Check the door lock, shelves, or other objects, make sure door is well closed.
Check the sealing rubber, make sure door is well sealed.
Check the door hinges, make sure they are not loose
Condenser is dusty Wash and clean the condenser
Cooling system faulty (Gas leakage or blockage) Ask engineer for help
Compressor start
and stop frequently
The door gasket does not seal properly. Use hair dryer to blow hot air and make the door seal smooth.
The sensor connection is wrong. According to the wiring diagram and make the correct connection of sensor
The sensor is faulty. Replace with new sensor
The door is opened too often. Reduce the times / frequency of door opening.
The light does not
work. Not plugged in, or the light button is “OFF”.
Light itself faulty or PCB faulty.
Check and make sure the light button is ON, or ask engineer for help.
The Refrigerator
seems to make too
much noise.
The stand feet is not leveling, vibrations lead to noise Adjust the stand feet and assure they are on level.
Pipe hit other objects and lead to noise Adjust the position of pipe slightly
At the moment of compressor shut down or start, it is normal for
the noise from the vibration generated by the internal moving parts
due to inertial motion.
nothing is necessary
The ratting noise may come from the flow of the refrigerator, which
is normal. As each cycle ends, you may hear gurgling sounds
nothing is necessary
The door will not
close properly.
Door is blocked by the door lock, shelves, or other objects. Remove the barrier
Door sealing rubber is deformed Repair or replace the rubber seal
Door hinges are not loose. Adjust and fasten the hinges.
Ice up
Outlet / suction outlet blockage Remove the barrier
Fans stop working or low speed operating
Ask engineer for help, power on the cooler, check the fan whether the voltage is normal or not. If
the voltage is not normal, it should be PCB or circuit faulty. If the voltage is normal, the fan
should be damage
The door gasket does not seal properly;
or door is opened too often
Use hair dryer to blow hot air and make the door seal smooth.
Gas leakage or cooling system blockage Ask engineer for help
External cabinet
seems too hot
Ambient temperature is too high, or direct sunshine Using conditions need to be improved
Front grill outlet / suction outlet blockage Remove the barrier
Fans stop working or low speed operating
Ask engineer for help, power on the cooler, check the fan whether the voltage is normal or not. If
the voltage is not normal, it should be PCB or circuit faulty. If the voltage is normal, the fan
should be damage
Water drop on glass
door
Ambient humidity is high Use a soft cloth to clean the water
Door is opened too often Reduce the times / frequency of door opening.
The door gasket does not seal properly Use hair dryer to blow hot air and make the door seal smooth.
