4-2-7. When an error occurs in self diagnostic mode (in case of a sensor error)

- A sensor error is displayed on the front display panel of the refrigerator. If a sensor error is detected when the power is supplied to the refrigerator for the
first time, the sensor error message is displayed on the display panel.
- Even if a sensor error occurs during an operation, the refrigerator does not stop. However, the refrigerator operates in emergency operating mode and
the cooling operation may not be performed properly. Therefore, in this case, check the refrigerator referring to the self diagnostic section in this manual.
① When the "13E" (humidity sensor) or "16E" (internal humidity sensor) error occurs
☞ Check the i n put vol t age to the humi d i t y sensor
Humi d i t y sensor operati n g vol t age: 5 V
Check i f 5 V i s measured at the humi d i t y sensor
connectors #1-#2.
☞ Check the output vol t age from the humi d i t y sensor
Check the vol t ages of the humi d i t y sensor
connectors #1-#4 referri n g to the humi d i t y sensor
vol t age tabl e .
② When the "2E" (fridge temperature sensor) error occurs. (Please also check the other sensors by applying these
troubleshooting procedures.)
Refer to the descriptions about the
circuit operation and how to check
the temperature sensor.
Start
