English

Meaning

Communication error between the display panel and main control board. The display panel exchanges button commands and display data with the main board via serial communication.

Common Causes

1. Display panel to main board wiring harness broken
2. Connector terminals corroded
3. Display board MCU fault
4. Main board communication circuit damaged

Self-Check Steps

1. Check whether the display is completely black or shows garbled characters.
2. Power off the refrigerator for 5 minutes, then power on and check if the display returns to normal.
3. Inspect the wiring harness at the door hinge for damage from repeated door opening and closing.
4. If the display intermittently works and fails, the connector may be loose; open the panel to check.
5. If a communication fault is confirmed and it is not a wiring issue, the display board or main board needs replacement; contact Hisense service.
