Step 4: If the fault still occurs, replace the main PCB.
Water tank
installation failure
Step 1: Check whether the water tank is installed in place, pull out the
water tank and install it again;
Step 2: Check whether the connection terminals behind the water
tank seat is plugged in place and whether there are foreign matters in
it; after cleaning the terminal, plug it in again.
Step 3: Check whether the switch in the water tank seat is damaged,
replace a new switch.
Ice-flipping 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.
Main control
board-
communication
fault of ice-making
board
Step 1: Check whether the connection terminal on the icemaker
control PCB, 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
icemaker control board and the main PCB to see if it is broken. If test
value is ∞Ω, the wire is broken.
Step 3: If the wire is OK, replace the icemaker control board.
Step 4: If the fault still occurs, replace the main PCB.

fault of ice-making
board
Step 1: Check whether the connection terminal on the icemaker
control PCB, hinge cover and icemaker display panel 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
icemaker control PCB and the icemaker display panel 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 icemaker display panel.
Step 4: If the fault still occurs, replace the icemaker control PCB.
