Corrective Action
1. Check whether the terminal CN1 is connected properly or not, pull out the terminal
and re-connect in place. Clean if any foreign particles trapped inside the terminal.
2. Take out the refrigerating sensor (see section Temperature Sensor) and inspect the
sensor against the resistance value table in Resistance Value of Sensor (R/T).
3. Replace the main control board. See section Main Control Panel.
4. Replace the main wiring harness.
1. Check whether the terminal CN1 is connected properly or not, pull out the terminal
and re-connect in place. Clean if any foreign particles trapped inside the terminal.
2. Take out the freezing sensor (see section Temperature Sensor) and inspect the
sensor against the resistance value table in Resistance Value of Sensor (R/T).
3. Replace the main control board. See section Main Control Panel.
4. Replace the main wiring harness.
1. Check whether the terminal CN3 is connected properly or not, pull out the terminal
and re-connect in place. Clean if any foreign particles trapped inside the terminal.
2. Take out the defrost sensor in fresh-food compartment (see section Defrost Sensor)
and inspect the sensor against the resistance value table in Resistance Value of
Sensor (R/T).
3. Replace the main control board. See section Main Control Panel.
4. Replace the main wiring harness.
1. Check whether the terminal CN3 is connected properly or not, pull out the terminal
and re-connect in place. Clean if any foreign particles trapped inside the terminal.
2. Take out the defrost sensor in freezer compartment (see section Defrost Sensor) and
inspect the sensor against the resistance value table in Resistance Value of Sensor
(R/T).
3. Replace the main control board. See section Main Control Panel.
4. Replace the main wiring harness.
1. Check whether the terminal CN8 of the main control board is connected properly or
not, pull out the terminal and re-connect in place. Clean if any foreign particles
trapped inside the terminal.
2. Replace the main control board. See section Main Control Panel.
3. Replace the display control board. See section Display Control Panel.
4. Check whether the cables of the main display board are connected properly or not.
1. Check whether the terminal CN2 of main control board is connected properly or not,
pull out the terminal and re-connect in place. Clean if any foreign particles trapped
inside the terminal.
2. Check whether the sensor wiring harness is connected properly or not.
3. Replace the main control board. See section Main Control Panel.
4. Remove and replace the temperature and humidity sensor at the door hinge. See
section Ambient Temperature and Humidity Sensor.
