Possible Causes
Failed touchpad or button PCB, Loose ribbon cable between UI and main board, Corroded keypad connector
How to Fix / Troubleshooting
Safety first: Disconnect power before opening the control panel.
- Inspect keypad cable: Remove the front control panel. Locate the flat ribbon cable or harness connecting the keypad to the main control board. Ensure it is fully seated and not damaged.
- Clean contacts: If the connector shows signs of corrosion, gently clean it with electrical contact cleaner and a soft brush, then reconnect firmly.
- Check for stuck buttons: Press each button individually and feel for proper travel. If any button is stuck or the overlay is damaged, the keypad assembly may need replacement.
- Test operation: Reassemble the panel, plug in the smoker, and test all buttons. If E7 remains, replace the keypad/user interface module or the entire control panel assembly as specified for your Cuisinart model.
