△Cooling system faults
○How to diagnose faults:
It should take approximate 3 hours to reach the lowest setting temperature for an empty unit of both compartments
(assuming ambient temp of 32 degrees centigrade and continuous operation). If not, check the compressor, cooling fans,
controller, and sensors. If all these are working normally, there is probably a cooling pipe fault.
○Maintain the faults：
1. Check the compressor
If two zones can not refrigerate, check the rated current of the compressor with a caliper type Amp meter, and the
current should be within 0.8 to 2 Amps. If the current not in this range, turn off and cut off the pipes (Fig.5 and Fig5.1, see
point D & Fig.5 and Fig.5.1, see point A) from the compressor. Then turn on the unit and check there is electricity current
flowing to the compressor ,and check if there is pressure at the outlet pipe, If the current reading is still out of range
specified above or no pressure from the compressor outlet, replace the whole compressor .(Noted: Turn on the compressor
which cut pipe not longer than 15 minuets in order to avoid suck moist air)
2. check the cooling system pipe work
2.1>. Under the condition of the compressor normally running situation, the two zones do not refrigerate, and it is
possibly the refrigeration system leak. The maintain procedure is following.
a. Cut off discharge pipe from compressor and charge with refrigerant to 0.8—1Mpa nitrogen via the process pipe.
Then place your hand close to the broken end of discharge pipe, if you can feel a little airflow, this proves the capillary
is normal, if not it means the capillary is jammed. (Noted: There are two capillarys in synchronous dual temperature
wine cellar. If the flowing direction of refrigerant valve is not changed, you can feel a little airflow from only one of
capillary, if not, please change the flowing direction of refrigerant valve. See Page 12)
b. Weld the broken discharge pipe if capillary works normal, then charge to 0.8—1Mpa nitrogen via the process
pipe and check if there are any leaks from every soldered joint of the cooling system using soapy water and looking for
tiny bubbles, Check the soldered joints around the compressor first (Fig.5 & Fig.5.1), then check the soldered joints
around the evaporator see (Fig.3). Remove the air duct board when you check the evaporator joints, see (Fig.1&Fig.2).
c. If there are no leaks as the b item. The faults maybe :
①A leak in the condenser or anti-dew pipe. This internal leaks cannot be repaired, and it can be replaced with the
new one of the same module.
②Or a fault of other components in the unit, please replace the same module.
d.. If there are no leaks in the cooling system pipe work, please refill refrigerant
2.>.When the compressor work normally, one zone did not refrigerate, the fault is due to the component of one

6
zone. The maintain procedure is as following (The structure of two zone is the same, and here we only recommend one
method).
a. Check the refrigerant valve, and check the voice. Turn off the power, exchange two poles of the refrigerant valve,
then turn on the power, and listen that it will move with a snip-snap, otherwise it is out of power or the refrigerant
valve is fault.. Confirm that the circuit board is normal, and replace the same module’s refrigerant valve. (→12) (Fig.9)
b. If the refrigerant valve work normally, the fault capillary may jammed. The examination method is as above.
c. Replace the fault spare parts. Confirming the cooling system is not jammed, refill the refrigerant.
3.Refill the refrigerant:
1>. Using the vacuum pump from a vacuum in the system, via the joint of the low-pressure pipe which on the process
pipe of compressor (→5、→6) (Fig.5, Fig.5.1 showing A), the high-pressure pipeline which on the process pipe of the drain
filter (Fig.5, Fig.5.1 showing G). Apply the vacuum pump for approximately 20 minutes. Until the vacuum is lower than
100Pa. Then solder the drainpipe. Keep the vacuum running while soldering this joint
2>. Fill Cooling system with refrigerant via the process pipe (→5、→6) (Fig.5, Fig.5.1 showing A). (The refrigerant is
R134a. Regarding refrigerant quantity, please refer to the instruction at back label of wine cellar). Then solder the
compressor process pipe after the system is charged with refrigerant.
4. Running test.
Fit all the components after the above procedures and turn the unit on. To verify the effectiveness of the repair, monitor
the unit the compressor should automatically stop within + or - 2.5 deg centigrade of the set temperature within approx 3
hours (assuming an ambient temperature of 32℃and the unit is empty)

○How to remove the air duct board
1.Take out the shelves before remove the air duct board. Normally there are three way to fix the shelf.
1> Fixing block installation
Flatly pull the shelf to the corresponding indentation, and then upper the shelf and drag out of it (Fig.1)
2> Side rail installation
Flatly draw off the shelf to the end, then raise upper the shelf and drag it out.(Fig.1.1)
3> Low rail installation
As same as fixing block installation (Fig.1)
2.There are three kinds of air duct board
1>. For normal dual temperature model
a. Remove the screw (1) of top middle air duct board cover (A) and take the cover (A) out (Fig.2.1)
b. Unplug all the connectors of PCB board, except transformer and display panel, then remove 4 screws (2) on low air duct
board and take it out carefully (Fig.2.2).

▲Noise problems
○Compressor noise
1. The working of motor and piston motion will cause noise when compressor working. So if noise is steady and not
exceeds 42 dB, it’s normal. If noise is not steady or very high, it’s compressor fault and it should be maintained or replaced.
2. If compressor’s shock absorption rubber is hardening or damaged, or fixing screw of compressor is too tight or loose, it
will cause noise. The settlement is to change new shock absorption rubber or adjust fixing screws.
○Fan noise
1. When the fans are running , the vanes are circumrotating rapidly and the air flows, which will cause steady and standard
noise. The noise should not exceed 32dB and it is normal.
2. If the noise is extremely high and abnormal, the cause maybe as below
1>. The axis of the fan is broken
2>. The fan is broken and lost balance
3. If the fan is broken, please replace the same specification’s one. According difference model, there are three kinds of fan
1>. For Synchronous Dual Temperature wine cellar (Note: the way to replace upper compartment’s fan is as same as lower
compartment’s fan)
a. Remove the shelves. (→3) (Fig.1 & Fig.1.1)
Fig. 6

11
b. Remove the air duct board (→5) (Fig.2.1 & Fig.2.2 & Fig.2.3)
c. Remove 4 screws (1), the replace the fan. (Fig.6)
Fig.6.1
3>. For normal two temperature wine cellar
The way to replay fan after air duct board is as same as synchronous dual temperature wine cellar (→6) (Fig.6)
Below is how to replace the fan in middle air duct board.
a. Remove the shelves (→3) (Fig.1 & Fig.1.1)
b. Remove 8 screws (1), then take out fan cover（Fig.6.2）. Remove 3 screws (2), then take out lower middle air duct board
& unplug fan’s connector, replace the fan（Fig.6.3）
4>. How to replace condenser fan.
a. Remove snap rings (A), take out compressor electrical’s cover (→9) (Fig.7)
b. Mark relevant note on connector (C & D), then unplug them (→9) (Fig.7)
c. Move the upper body backwards and down 45℃
or put it on table and let the compressor support bracket suspend.
Remove 2 screws (1 & 2), the replace the fan (→9) (Fig.7 & Fig.7.1)
(Note: For the model with separated PCB board, the fan’s connect is on power PCB board. Please refer to how to remove
power PCB board and transformer, remove PCB board cover first, then unplug fan’s connector, replay the fan (→15)

○Refrigerant jet noise
Default: It is continuous noise like a water spray from the capillary.
Reason: The end of the capillary is in the wrong position, or there are rough edges on the end of the capillary.
Solution:
1>. Heat the soldered joint of the capillary (→5)（Fig.3, A）, then remove the capillary from the evaporator and smooth the
end with rasp. (Caution: do not allow any particles into capillary)
2>. Insert the capillary into the evaporator, then solder it back into the correct position (not exceeding 15mm in the
evaporator) and pack the joint with anti vibration compound
3>. Refill with refrigerant. (→4)
○Capillary vibration noise
Default: High frequency impact noise in capillary.
Caused by either reason below:
1>. The capillary being insert too deep into the evaporator, so when the refrigerant is Jetting, the end of vibrating capillary
will hit the inside of the evaporator.
2>. Vibration from the capillary touching the inside of the cabinet or air duct board, then when refrigerant is jetting.
Solutions:
1>. If the capillary is inserted too deep, heat it with the solder, and solder it again(Please noted, the deep inserted is not
longer than 15mm), and vacuumize it and refill the refrigerant. (→4).
2>. If the capillary touch the inner cabinet and the air duct panel, adjust the position of the capillary and add the anti
vibration compound (→5) (Fig.3 ).
○Oil jammed noise
Fault: intermittent and deep jet noise coming from inside of the capillary.
Cause: Compressor oil flowing into the cooling system pipe work probably due to the capillary slightly out of alignment
during transportation.
Fig. 7 Fig. 7.1

14
Solution: Clean the cooling system pipe, vacuumize it and refill with refrigerant. See (→4)
▲Evaporator freezing
○Because the door seal is not air-proof, or the door is not closed well, cause much water fill in the cabinet, and the
water got frozen when it encounter the cold air, sometimes the ice is too thick, and it will block the fan or broken the fan.
The solution:
1 >. Replace the door seal or close the door well. If the door seal is slightly not air-proof, it can be repaired by the heat dryer.
Aiming at the distortion of the seal with the heat dryer, and move up and down until it expand to the normal state. When it is
cool, check it with the door closed, if there is any distortion, dry it again until it fix for the door. See (Fig.8)
▲The instability of the wine cellar temperature
The instability temperature is caused by evaporator’s fan on/off.
Solution: When the compressor is on, the indicator light on control panel is on, the fan should be running. If not, check the
fan’s connector & fan. Once the fan is fault, please replace a new one (→8) (Fig. 6 & Fig. 6.1 & Fig. 6.2 & Fig. 6.3)
▲Control system problems
○Fault finding by the self-check mode
Because this series’ wine cooler is electrical controlled, in order to maintain and repair the wine coolers.
There is self-check function in the PCB board. If there is any default of PCB system, please start the self-check system. The
method is as below.
1 >．Press and hold “Set lower”
and “Set upper” button with power on. 2 beeps will sound, and then the controller will start
the self-check function
2 >．If everything is operating correctly,：
a. No response when pressing buttons.
b. LED reader display “——”
Fig. 8

15
c. The compressor works and the “RUN”
indicator light are on all the time.
d. The evaporator fan and condenser fan should be work. The refrigerant valve is on all the time.
e. The switch controls the light functions normally.
3 >．If the situation fit for a~e statement, the spare parts are normal, if the control panel and the various components of the
unit do not respond as above check the faulty part and relevant connection. If this does not cure the fault replace the control
board. (→13、→14、→15、) ( Fig.10.1 & Fig.11& Fig.12& Fig.13& Fig.14.1& Fig.14.2)
4 >．To return the control panel to its normal working mode unplug the unit and plug it in again
○Fault synchronous dual temperature model
1>. The LED display show HI, it is the high temperature protection indication. The elements is that machine will self-test
after turning on 10 hours. If inner temperature is over 23℃, LED display show HI. Once it persist for 1 hour, LED display
flash “HI” and beeper alarm is start. After beeper larm more than 20 minutes, compressor will be forced to stop, beeper
alarm stop but HI code is still flash until turn off the machine.
Solution:
A. If LED display of two compartments bother show HI, it cause by gas leak. Please find the maintain procedure to Page 4
B. If LED display of one compartment show HI, it case as below:
a. The capillary is jamed. Please find the maintain procedure to Page 4
b. The refrigerant value is fault, please replace a new one. (→12) (Fig.9)
c. The evaporator fan is fault, please replace a new one. (→7) (Fig. 6& Fig.6.1)
2>. The LED display show LO, it is the low temperature protection indication. The elements is when the temperature of
the cabinet is lower than 0℃, the system start up low temperature protection function, and now the LED display shows LO. ,
and the buzzer alarm, the machine is forced to stop, so as to protect the wine from damage. When the temperature of the
cabinet is higher than 0℃, the protection will dismiss automatically, and the LED display show the actual temperature.
Note: the LO usually appear when the temperature set between 4~6℃, if the temperature set higher than 6℃, LO appear,
and it is abnormal, the resolution is check whether there is any voltage outlet the refrigerant valve , if no, change the control
board.
○Sensor fault
Accorcding different model, there are 3 kinds of sensor
1. For synchronous dual temperature wine cellar’s sensor
1>. After turning on the power, if the LED display shows the temperature is similar with the ambient temperature, it is
normal, if abnormal, please remove air duct board (→5、→14) (Fig.2.1 & Fig.11& Fig.12), check the sensor connecter is
well, if yes, the sensor is fault, please replace a new one.
a．The LED display shows E7, and it is the lower compartment sensor’s fault, check the connection wire and the main board
