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 control PCB.
Ambient temperature
sensor fault
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 control 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 control PCB.
Defrost sensor fault in
variable chamber
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.
Sensor fault at the
bottom of freeze ice
maker
Step 1: Check whether the connection terminal s on the ice
maker and the main control 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 multi meter 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 control PCB.
Sensor fault at the
bottom of freeze ice
maker
Ice-flipping fault of
refrigerating ice maker
Step 1: Check whether the connection terminals on the ice
maker and the main control PCB are plugged in place and
whether there are foreign matters in them; after cleaning the
terminals, plug them in again.
