Refrigerator chamber
sensor failure (E1)
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.

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.
