9.5 Open door alarm
If refrigerator door or freezer door is open last for 120s, there will be a buzzer alarm, afterwards give
alarm one time per second until the door is closed, or press any buttons on control panel can cancel this
buzzer alarm.
Note: When open the door, the display panel will light on. When the door is closed, the display panel
will be light off after 30s if there is no any operation on display panel.
9.6 Error code and solutions
Note: Midea full common fault code, combined with the actual product display reference.
Troubleshooting and Solutions
Initialization fault of
freeze 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.
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 control 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 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.
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 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
freezing chamber
Defrosting fault of ice-
making compartment
Main control PCB and
Display control PCB
communication fails
Step 1: Check whether the connection terminal on the display
control panel, hinge cover and 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 all connection terminals,
use a multimeter to check the resistance value of the wire
between the display control board and the main control PCB to
