1. Repair work safety precautions (please follow below precautions before maintenance)
DANGER
• Do not use open flames indoor or smoke during reqairing.
• Do not perform welding in poorly ventilated and confined areas
• Do not have children nearby when reparing
WA R N I N G
•Always unplug the power cord first before carrying out maintenance
Otherwise, it may result in electric shock and injuries.
•Please be careful not to get electric shock during reparing.
Unplug the power cord before maintenance. If needs to check the circuit while the
power is on,do not touch the live electrical parts! If electric wires are damaged, it
must be replaced by qualified technician in time.
• Use original parts which shown in the part list, do not use parts from other models
or other brands, never modify the parts
• Use appropriate maintenance tools, improper use of tools may cause insecure
assembly
• If wires are cut during maintenance. Remember to reconnect the wire and seal with
insulating tape
•When discharging the refrigerant, make sure the room is in good ventilation
condition.
•When cutting off the compressor pipes, pay attention to the remaining refrigerant
and internal pressure.
• After maintenance finished, use multimeter to check the insulation, makesurethe
insulation resistance is over 2 MΩ before connecting to power.
•After repair, it is necessary to check whether the grounding is in good condition

NOTICE
Be careful to the high temperature of compressor and refrigeration pipes when
product is on or just after the production was power off.
Be careful to the high temperature after soldering
Be careful not to let liquid refrigerant directly touches the skin,it may cause
frostbit
Metal parts and plastic parts burr may scratch the hand.

6.3 Handling of common problems
PROBLEM POSSIBLE CAUSES
Appliance is not cooling Appliance is not plugged in
Appliance is not turned on
Check if voltage of the installation
Check the circuit breaker or if fuse has blown
Appliance is not cold
enough Check the temperature control setting Check if ambient temperature is beyond appliance operating temperature
The door is opened too frequently
The door is not closed properly
The door is not sealing properly
Check if wine cooler is exposed to sunlight or there has a heat source nearby
Insufficient free space around the appliance
Check if too many wine bottles have block the air ventilation hole
The compressor starts
and stops frequently The external temperature is high. A large quantity of bottles has been put into the cellar.
The appliance is opened frequently.
The door is not properly closed.
The cellar has not been correctly set.
LED lights do not operate The appliance is not plugged in
The fuse has blown
LED lights are not broken
The light switch is off
Vibration Check and ensure that the appliance is leve
l
The appliance makes a
lot of noise A noise resembling circulating water is produced by the coolant gas and this is normal.
At the end of a cooling cycle, you can hear the noise of water circulating.
Expansion and contraction of the internal walls may cause a cracking sound.
The appliance is not level
Check if fan is in good condition
The door does not close
properly The appliance is not level. The door seal is dirty or damaged.
The shelves are not positioned correctly.
A part of the contents is preventing the door from closing.
LED display is not
working properly Controlpanelfailed Power PCB has broken
The appliance is not plugged in
The probe is not working
Condensed water on the
door glass It’s normal when ambient temperature is too high or ambient humidity is too high.
