7. How to overhaul the default
It should take approximate 3 hours to reach the lowest setting temperature of
about 5℃ for an empty unit
(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.
7.1. Check the compressor
If the wine cooler not cooling, check the current with the Amp meter，refer to rating label, if it too high or too
low, cut the discharge pipe (Fig.15 item E) and (Fig.15 item C), power on, check the current, and feel the
discharge pipe, if the obvious air pressure from compressor, if the current still very high or very low or the
discharge pipe with small air pressure, the compressor fault, replace the compressor please.
Notice. After cut the discharge pipe and process pipe, in case of suck the damp, the compressor should ne
power on long time (no exceed 15 minutes is best).
7.2. Check the cooling system
When it is sure that the compressor is working normally and the cooling system’s fault is concentrating on
the cooling system pipe. Check following below:
1>.Cut off process pipe and check the refrigerant. If there is not enough refrigerant, the default of the
refrigerant system should be caused by the leaking. If the refrigerant is sufficient. it is probably block in
the capillary.
18/23
2>.If the default is concentrated on the cooling system, the checking procedure is as below.
a. Cut off the discharge pipe (See Fig.13, E) of the compressor, and infuse 0.8-1.5 MP nitrogen per
process pipe, and put the hand close to the cut kerf. If there is a little gas leak from the terminal, it
means normal, otherwise it is jammed.
b . Make sure the capillary is working normally. Then reconnect the discharge pipe, and infuse
0.8-1.5 MP nitrogen from process pipe, then test the leakage, check with soap water if the cooling
system of the soldering point is damaged. Check from the soldering point around the
compressor(Fig.13), if it is OK, then check the soldering point of the evaporator(Fig.16 ), before
check please remove the air-duct board, please see the remove method and procedure in (→6.1.2)
c. If all the soldering point in b is not leaking, there are two possibility, one is leakage in the inner
condenser (or anti- dew pipe), another is the damage on the spare parts in the cooling system. If it is
the inner damage, it can not be repaired, and if the damage on the spare parts, replace them.
3>. Make sure there is no leakage in the cooling system, infuse the refrigerant.
7.3.
Refill the refrigerant:
1>.Using the vacuum pump form a vacuum in the system, via the joints of the low-pressure pipe, the
low-pressure pipeline is on the process pipe of the compressor (Fig.13, C). Apply the vacuum pump for
approximately 20 minutes. Until the vacuum is lower than 100Pa.
2>. Fill Cooling system with refrigerant via the process pipe of the compressor (Fig.13, C). (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.
7.4.
Running test:
After the procedures above finish, 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).
19/23
7.5.
Noise problem
1 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. （→6.2.3）
2 Fan 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. （→6.2.3）
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. （→6.2.3）（→6.2.2）
7.6.
Refrigerant jet noise
Default: There 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>. Remove the evaporator（→6.2.4）, heat the soldered joint of the capillary （Fig.3）, then remove the
capillary from the evaporator and smooth the end with an eraser. (Caution: do not allow any
particles into capillary unit).
2>. Replace 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>. Recharge with refrigerant. （→7.3）
7.7.
Capillary vibration noise
20/23
Default: high frequency impact noise in capillary Zone.
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>. Refer to（→7.6）
2>. If the capillary touch the inner cabinet and the air duct panel, adjust the position of the capillary and
add the incabloc plastic.
7.8. 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
Solution: Clean the cooling system pipe, vacuumize it and recharge with refrigerant see （→7.3）
7.9.
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. (Fig.18)
2 >. If the fan is broken, replace the fan.
21/23
Fig.18
7.10. Unstable temperatures inside the cabinet.
The unstable temperature is caused by the evaporator fans cease, and it can be check by the below method:
When the compressor is running, the light “Run” is on, the fan should be running, if the fan stop, check the
whether is any fault in the fan or fan connection. If the fan is broken, replace it with the fan of the same
model . （→6.1.3）
7.11.
The digital display’s fault
This malfunction is caused by the display of main PCB default, replace with the same model’s main PCB.（→
6.1.6）
7.12. Sensor default
The process: remove the shelves → remove the control box → remove the air-duct board →
remove the sensor
(→6.1.4.)
1 >．After turning on the power, if the LED display shows the temperature is similar with the ambient
temperature, it is normal, if abnormal or show ‘E1, E2’ , please remove the control box, check the sensor
insert whether reliable (Fig.5). If the insert is reliable, it is the sensor’s fault, replace the sensor with the
same module. (Fig.1, Fig.2, Fig.3);
2 >．If the LED display show ‘E3, E4’, it is the defrost sensor problem. Remark: The defrost sensor is in
the foam body, if the sensor faulty, just place the replace sensor in the control box.
How to replace the sensor:
Cut the sensor, the rest wiring should be long enough to reconnect. Peel off the scarfskin about 12mm, cut
the spare sensor and peel off it’s scarfskin about 12 mm, connect the ends, and wrap the ends with
insulating tape. Fix the sensor on the original position.
22/23
7.13. Explanation of display.
According to requirement there are two different display, one is that the LED display show the setting
temperature, the other is that the LED display show the real inner temperature.
