Possible Causes
Failed capacitive touch panel, Loose ribbon cable to control board, Moisture under control panel, Faulty main control board interface
How to Fix / Troubleshooting
Safety first: Unplug the unit before accessing the control panel.
- Power reset: Unplug for 10 minutes, then reconnect and test. This can clear minor logic glitches.
- Dry the panel: If the panel was recently cleaned with liquid, allow it to dry completely. Do not spray cleaner directly on the panel; apply to a cloth instead.
- Check ribbon cable (advanced): Remove the top cover and reseat the ribbon cable between the touch panel and main board.
- Replace touch panel: If specific buttons never respond, replace the touch control panel assembly.
- Replace control board: If a new panel does not resolve the issue, the main control board may be defective.
