■TROUBLESHOOTING
◆The solution for digital display code problem:
There are total 2 sensors，one is near Evaporator which can be only seen when open wind channel plate
in freezer chamber,this is evaporator temperature sensor. The other is in Freezer Chamber room，
touching the temperature, which is temperature control capillary tube(the temperature sensor inside the
cabinet).
Considering the Sensor connecting or cutting problem, in order to check the problem easier, we get the
display error to distinguish the problem when we design the product.
When the digital display window shows ‘E1’ that means the circuit of the temperature sensor inside the
cabinet is open circuit or short circuit,
When the digital display window shows ‘E2’ that means the circuit of the defrost sensor(evaporator
temperature sensor) is open circuit or short circuit.
The digital display window shows ‘E3’ that means the temperature sensor inside the cabinet and the
defrost sensor occur both fault.
Both sensors are connected on the main board which realize the connection. So when display shows
Erro problem, we need to check the sensor itself have problem or not，meanwhile, need to check the
connect well or not between the sensors and main board.
Detail method show below:
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 solution for “E1”problem
Open the door and put out the drawer
7
The location of the sensor inside the cabinet
Open the sensor cover with you finger
Put off the sensor cover
Using the multimeter with the ohm switch to measure
the resistor of sensor, if sensor is bad ,change a new one.
Or else ,go on next step.
Measure the resistor of plug, If the resistance figure shows
infinity, that means connection between the main board and
plug have problem.
8
Unscrew the top Cover’s screws
Remove the top cover
Remove the electron box cover
Checking the connection of main board have problem
or not.
The solution for “E2”problem:
9
Open the door and put out all the drawers
Remove the wind channel plate in freezer chamber.
Put off the foam
The location of the evaporator temperature sensor always
fixed on the suction tube as attached (sometimes it fixed on
the right middle of the evaporator).
Take off the evaporator temperature sensor ,and Measure the
resistor , if sensor is bad ,change a new one.
Meanwhile, measure the resistor of wire plug, If the resistance
figure shows infinity, that means connection between the main
board and wire plug have problem. the detail method as
above.
The solution for “E3”problem:
According to above two principle, to check both above
◆The common problem judgement method
Problem Cause
Refrigerator can’t 1.1 Is the power cord connecting well？
