sensor fault
and whether there are foreign matters in them; after cleaning the
terminals, plug them in again.
Step 2 : If the fault still occurs, pull out the corresponding connection
terminal on the main PCB, use a multimeter to check the resistance
value of the sensor, and confirm whether it is normal.
Step 3 : If the resistance value is wrong, replace the sensor.
Step 4 : If the fault still occurs, replace the main PCB.
E8
Defrost sensor
fault in variable
chamber
E9
High temperature
alarm in freezing
chamber
Step 1 : Check whether the door is not closed, or whether there is
leakage between the door gasket and the cabinet.
Step 2 : Check whether the door gasket is deformed and causes
leakage, reshape or replaced with a new one.
Step 3 : Check whether the freezing frost is OK, if there is ice on the
evaporator and the fan motor is frozen, replace a new defroster
heater.
Step 4 : Check whether the light switch is damaged, replace new one.
Step 5 : Check whether the freezer fan stops working, plug and unplug
connection terminals, replace a new fan motor.
Step 6 : Check if the pipeline is leaking or blocked. After maintenance,
vacuum and refill the refrigerant.
EE
Sensor fault at the
bottom of freeze
ice maker
Step 1 : Check whether the connection terminal s on the ice maker
and the main PCB are plugged in place and whether there are foreign
matters in them; after cleaning the terminals, plug them in again.
Step 2 : If the fault still occurs, pull out the connection terminal on ice
maker, use a multimeter to check the resistance value of the sensor,
and confirm whether it is normal.
Step 3 : If the resistance value is wrong, replace the sensor.
Step 4 : If the fault still occurs, replace the main PCB.
F4
Sensor fault at the
bottom of freeze
ice maker
F5
Ice-flipping fault of
refrigerating ice
maker
Step 1 : Check whether the connection terminals on the ice maker and
the main PCB are plugged in place and whether there are foreign
matters in them; after cleaning the terminals, plug them in again.
Step 2 : Enter the forced ice making mode and check whether the ice
maker works normally.
Step 3 : If the ice maker does not work, replace the ice motor.
Step 4 : If the fault still occurs, replace the main PCB.
F6
Initialization fault
of refrigerating ice
maker
EH
Circuit fault of
ambient humidity
sensor
Step 1 : Check whether the connection terminal s in the hinge cover
and the main PCB are plugged in place and whether there are foreign
matters in them; after cleaning the terminals, plug them in again.
Step 2 : If the fault still occurs, pull out the connection terminal on the
hinge cover, use a multimeter to check the voltage value of the
sensor, and confirm whether it is normal.
Step 3 : If the voltage value is wrong, replace the sensor.
