Troubleshooting and Solutions
Initialization fault
of freeze 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.
Temperature
sensor fault in
refrigerating
chamber
Step 1: Check whether the connection terminals 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 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.
Temperature
sensor fault in
freezing chamber
Temperature
sensor fault in
variable chamber
Sensor fault of
ice-making
compartment
Defrost sensor
fault in
refrigerating
chamber
Step 1: Check whether the connection terminals 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 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.
Defrost sensor
fault in freezing
chamber
Defrosting fault of
ice-making
compartment
Step 1: Check whether the connection terminal on the display control
panel, hinge cover and 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 all connection terminals, use a
multimeter to check the resistance value of the wire between the
display control board and the main PCB to see if it is broken. If test
value is ∞Ω, the wire is broken.(If the wire in the door is broken,
replace the door. Other conditions cannot be repaired.)
Step 3: If the wire is OK, replace the display control board.
Step 4: If the fault still occurs, replace the main PCB.
Step 1: Check whether the connection terminals are plugged in place
