How do I fix F12 error code on Maytag refrigerator?

The F12 error code on a Maytag refrigerator typically indicates a communication error between the central control unit (CCU) and the user interface control (UI). Here are a few troubleshooting steps you can try to fix this issue:

1. Check the wiring connections between the CCU and the UI. Make sure they are securely connected and not loose or damaged.
2. Unplug the refrigerator for at least 5 minutes and then plug it back in. This can sometimes reset the control board and clear the error code.
3. Check the UI. Make sure it is properly connected and not damaged. A faulty UI can cause the CCU to send an F12 error code.
4. Check the CCU. Make sure it is not damaged or burned. If the CCU is damaged, it will need to be replaced.
5. If none of the above steps fix the issue, it's likely that the UI, the CCU or the wiring between them needs to be replaced. It's best to contact a certified technician for this repair as it requires special tools and knowledge.
