Troubleshooting
◆ The solution for digital display code problem:
1
The digital display window
show “E3”
1. The freezer chamber Tem.
Sensor is open circuit or short
circuit.
2. The freezer chamber Tem.
Sensor is bad.
3. The control PCB is bad.
1. Using a Mult imeter with the ohm
switch to measure the resistor of
sensor or checking the connecting is
well or not.
2. Change the sensor
3. Change the control PCB
2
The digital display window
show “E4”
1. The Evaporator Defrost
Sensor is open circuit or short
circuit.
2. The Evapo
rator Defrost
Sensor is bad.
3. The control PCB is bad.
1. Using a Multimeter with the ohm
switch to measure the resistor of
sensor or checking the connecting is
well or not.
2. Change the sensor
3. Change the control PCB
3
The
digital display window
show “EC”
1. The receive communicat ion
fault between the main
electrical PCB and the display
PCB.
2. The control PCB is bad.
3. The display PCB is bad.
1. Check the wire terminal is well or
not between the main electrical PCB
and display PCB.
2. Change the main electrical PCB.
3. Change the display PCB.
4
The freezer digital display
window show “EF”
1. The Fan motor is open
circuit or short circuit.
2. The Fan motor is bad.
3. The control PCB is bad.
1. Using a Mult imeter with the ohm
switch to measure the resistor of Fan
motor or checking the connect ing is
well or not.
2. Change the Fan motor
3. Change the control PCB
The testing method of sensor：
Using the multimeter with the ohm switch to measure the resistor of sensor, normally at surrounding 25℃ the
resistor should be about 2kohm and every with the temperature decreases 1℃ the corresponding resistor value
would increase about 45ohm.If the measured value is not within the normal scope, the sensor is bad and needs
to repair or change.
◆ The common problem judgement method
Problem Cause
Refrigerator can’t start
1.1 Is the power cord connecting well？
1.2 Is the power voltage too low？
1.3 Is the sensor irrational setting?
1.4 Is the ambient temperature too low?
1.5 Is the circuit on power?
1.6 Is there some default in compressor
1.7 Is the refrigeration system blocked by ice or dirty, please stop the unit and restart
after 10 minutes to see if the compressor can start.
Weak cooling effects 2.1 Is there any heat source around the refrigerator?
