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

WAR NI 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

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

Applianceis 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 therehas 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 s tops 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 applianceis leve 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.

6.4 Diagnosis of problems

rRep

●Screen not display

Is there a display window of the

product?

The simple way (check the power

supply)

Check the display board to see if there is input voltage?

Display board Broken

Test the power (power cord, plugs,

sockets)

Check the control board and display

board

●Compressor doesn’t work

Is setting temperature lower

than ambient temperature?

Re‐set the

temperature

Does compressor work after

replace the compressor

protector?

Check the main power is on and display

works or not?

Defrost or not

Check the connectors in the power

PCB box if it is well‐connected

Cut the power,measure the

impedance of the compressor

protector if is <1Ω

(at room temperature)

Connect the power, measure whether

the compressor output terminals P1,

P2 on the main PCB have 220V output

to the compressor

Measure the impedance of

compressor to check if

it can meet the corresponding

Replace the main PCB

impedance standard

Replace PTC starte

Replace the compres

Lay down the cabinet (glass door facing up)

Unscrew the lower door hinge screws and take off lower door hinge. Then you can take off the door

to replace the new one.

7.9.Compressor

A. Dismantling the compressor:

1) Cut the gas filling pipe and slowly leak out the refrigerant gas.(1)

2) Cut the dehydrator, condenser pipe and evaporator pipe by using a weldinggun(2)

3) Unscrew the bolts on compressor base and remove the compressor (3)

7.10.Install a new compressor:

1)R e pl a ce the new compressor and connect the pipe of dehydrator,

condenser pipe and evaporator pipe (4)

2) Use a welding gun to weld the dehydrator, condenser pipe and evaporator pipe(5)

3)Afterwelding,evacuatedthecompressorandrefilltherefrigerantgas(6)

(Evacuate time≥15min，KPA≤15pa)

4) Sealing the gas filling pipe after refilling the gas(7)

5)Tidy up all pipe to avoid contacting with each other or touch the cabinet,in case there will have
