Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the air fryer before removing the control panel. Do not use excessive liquid cleaners on the panel.
Step-by-step checks:
- Panel cleaning: Wipe the touch surface with a soft, slightly damp cloth and mild detergent. Dry thoroughly. Grease films can interfere with capacitive touch.
- Power reset: Unplug for 10 minutes, then plug back in and test. Sometimes the touch controller can lock up.
- Access ribbon cable: Remove the front bezel or control panel screws to expose the flat ribbon cable. Reseat both ends carefully.
- Inspect for cracks: Examine the touch PCB for hairline cracks, especially near mounting screws. Flexing can break traces.
- Test specific keys: After reassembly, test each button. If entire rows or columns fail, the touch panel assembly is likely defective.
When to stop: If reseating and cleaning do not restore function, replace the touch control panel assembly. Board-level repair is not practical for most users.
