9. Functions and features
9.1 Control panel
When powered on the display screen gives a full display for 3s then the panel displays normally. The
normal display area is lighted all the time and the temperature is displayed. If the system has an error, the
error code will be displayed. The first time the unit is powered on the temperature is shown in Celsius.
9.2 Temperature control
Temperature setting
● Press the Temperature-rise key, the temperature will increase 1℃ (or 1℉). After5s, the cooler will
operate according to the set temperature;
● Press the Temperature-drop key, the temperature will decrease 1℃ (or ℉). After 5s, the cooler will
operate according to the set temperature
● The beverage cooler‘s temperature can be set between -3~10℃（27~50℉）
Switching between Fahrenheit and Celsius
● Fahrenheit to Celsius: When the Fahrenheit temperature is displayed, press the key and it now displays
the Celsius temperature
● Celsius to Fahrenheit: When the Celsius temperature is displayed, press the key and it now displays the
Fahrenheit temperature

9.3 Error codes and solutions
Error Code
Failure Type
Solution
E1
Temperature sensor fault
1. Check whether the terminals CN3 and CN5 are secure,
pull out the terminal and replace it if necessary.
2. Check to see if there is foreign matter on the terminal.
3. Inspect the temperature sensor and test its
resistance. (See 10.3 & 10.8)
4. Replace main control board.
E4
Frost sensor fault
1. Check whether the terminal CN3 and CN5 are secure,
pull out the terminal and replace it if necessary.
2. Check to see if there is foreign matter on the terminal.
3. Inspect the frost sensor check whether contact is bad.
4. Replace main control board
9.4 Defrost function
The defrosting of the evaporator is activated when the temperature monitored by defrost sensor is below
set point. The compressor switches off, and following a temperature rise, the frost on evaporator
becomes water. The water flows into the water pan via the drain system and will eventually evaporate.
Page 24

10. Circuit description
10.1 Power PCB
AC input voltage is lowered by the transformer, then filtered by rectifier diode & LC into DC 12V.
The DC 12V controls the switches of compressor and defroster.
DC12V is changed through adjuster 7805 in to stable DC5V.
DC5V provides the power to the control chip.
The control chip monitors the temperature changes in the refrigerator.
If no power is detected in test, first check whether there is input voltage between the L& N line of
main PCB, if no input voltage(115V), check whether there is power supplied from the socket.
If there is input voltage, put the black probe of multi meter on the bottom of “GND” pin, and put
the red probe on the bottom of “+5v” or “+12v” pins. If “12v” or “5v” is detected, check whether
there is a loose wiring connection.
If there is no “12v” or “5v” it means the main PCB is defective. Replace it with a new one.
Page 25
24
10.2 Temperature circuit
During inspection unplug the wire connectors of the sensor (pictured above.)
Adjust the multi meter to detect the resistance, put the red probe and black probe on the
corresponding pins to detect the resistance value of sensor, then check with resistance table
(10.8) to identify whether the sensor is damaged.
Page 26
25
10.3 Refrigerator fan motor circuit
The fan motor runs with the compressor.
Check if there is 12V voltage between FAN pin and GND during normal operation.
There should be 6V or more between FAN pins.
If there is no voltage detected when the compressor is running, replace the fan motor or main
PCB with a new one.
Also adjust the multi meter to test for DC voltage.
Put the black probe on the GND pin and put the red probe on the FAN pin when the motor is
running.
There should be 6V or more detected.
When the fan motor is shutdown the detected voltage should be 0V.
