If the above a~e point is line in the situation, and every components of the machine is normal; if there is
any different, and firstly check the abnormal components and their connection wire. If the connection is tight,
replace the components. If the replacement fail, it can be judged as control PCB

s fault, please replace it with
the same module. ( Fig.10 & Fig.11)

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 the electrical box, (Fig.10 & Fig.11) (

The LED display shows HI, and it is the high temperature protection indication. After running 10
hours with power, if the inner temperature over 23
0
C. the LED display H I. When the HI shows for
an hour, then the HI twinkling , buzzer the alarm. And after the HI is continuous to twinkle for 20
minutes more, the compressor will stop working , and it need to be cut off power to stop the alarm.
The reason and the solution of this phenomena is as following.
A. If the left and the right side both show HI, the reason is refrigerant leakage cause the cooling
fault. Find the leakage point, and weld it again, vacuumize and refill. (

B. If any zone shows HI, the reason is as following
：
a. Because the capillary is blocked, not cooling, please do as the above method. (

b. The refrigerator valve damage and can not be switch, cause not cooling, replace with the new
one. (Fig.9)
c. The evaporator fan do not move, rapair it. (Fig. 5)

The LED display shows LO, it is the low temperature protection indication.The principle 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.
