What's Happening

The main control board and user interface board can't communicate. The control panel may be unresponsive or display garbled information. A loose ribbon cable between the boards is the most common cause.

How to Fix It

Disconnect power for 30 seconds. Check the ribbon cable connecting the boards. If secure, try replacing the user interface first (more common failure). If the error persists, the main board may need replacement.
