E5: E2PROM has a read and write failure.

E6: Over-temperature alarm, the freezing temperature continues to be too high.

E7: Communication failure.

E8: Zero crossing failed.

H: It indicates that the temperature in the corresponding temperature zone is too high.

L: Prompt that the temperature in the corresponding temperature zone is too low.

Open door alarm icon flashes: It is not a fault, prompting the user to close the door.

To troubleshoot the power supply, you only need to open the refrigerator door and see if the internal light is on and whether the wires are worn.

　2. There may also be a lack of refrigerant, which directly leads to no cooling, because many styles of refrigerators require refrigerant to start the cycle. The lack of refrigerant will directly cause the refrigerator compartment to start not cooling, which will then cause the air pipe to be blocked, and other areas will also have problems without cooling.

3. There is another reason that we cannot ignore, that is, the evaporator of the refrigerator has a frost problem, which will directly block the seal, and the cold energy cannot be discharged, which will affect the refrigeration of the refrigerator. Function.
