What to do if the Mijia Refrigerator Cross Door 510L displays UC?

If the Mijia Refrigerator Cross Door 510L displays UC, it means the display board has a communication failure.
The display board on the device serves as a center hub for interaction, which allows you to easily monitor and adjust settings such as temperature for both the refrigerator and freezer compartments.
If there is a communication failure, the cause of that is line blockage, display board failure, and a small probability of main board failure.
To solve the display board communication failure of the device, please refer to the following steps:
1. Turn off the power of the device for 5 minutes;
2. Turn it on after 5 minutes to observe.
If the problem is still not solved, please apply for after-sales inspection.
