Possible Causes

Worn touch membrane on specific keys, Contamination under control panel, Damaged UI ribbon cable tracks, Faulty user interface PCB

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.
