1. No fault code is designed: some refrigerators have no fault code function. This may be because the manufacturer did not consider the function of adding fault codes in the design stage, or this type of refrigerator does not need fault codes for fault diagnosis.
2. Fault code function is not enabled: Even if the refrigerator has fault code function, it may not be enabled. This may be because the manufacturer thinks that this type of refrigerator does not often break down, so the fault code function is not enabled.
3. Need a specific method to view the fault code: Some refrigerators may need a specific operation method or connect to a computer or display screen to view the fault code. If the fault code cannot be found, you may need to refer to the instructions of the refrigerator or contact the manufacturer for more detailed information.
It should be noted that even if there is no fault code in the refrigerator, the cause of the fault can still be determined by other means, such as observing the working state of the refrigerator, listening to abnormal noise, and checking the temperature of the cold room and the freezing room. If you encounter refrigerator failure, it is recommended that you consult the refrigerator manual or consult the manufacturer or maintenance professionals to obtain accurate fault diagnosis and solutions.
