How to Fix / Troubleshooting
Safety first: Unplug the air fryer before removing the control panel.
Steps to restore control:
- Clean surface: Wipe the control panel with a slightly damp cloth and dry thoroughly. Do not use excessive liquid.
- Inspect ribbon cable: Remove the front bezel and check the UI ribbon cable for kinks or cracks. Reseat both ends.
- Test all keys: After reassembly, test each button. If only certain keys fail, the touch membrane or UI PCB is likely defective.
- Replace UI assembly: Install a new touch control / user interface PCB assembly if cleaning and reseating do not resolve the issue.
