How to Fix / Troubleshooting
Safety first: Unplug the air fryer before removing the control panel.
- Step 1 – Power reset: Unplug for 10 minutes, then plug back in. Sometimes static or minor firmware glitches can lock the keypad.
- Step 2 – Clean surface: Wipe the control panel with a slightly damp cloth and mild detergent, then dry thoroughly. Do not spray cleaner directly onto the panel.
- Step 3 – Check for moisture: If the unit was recently cleaned heavily, allow it to dry for 24 hours and test again.
- Step 4 – Inspect ribbon cable: Remove the front bezel or top cover to access the control interface board. Reseat the flat ribbon cable or harness connecting it to the main control PCB.
- Step 5 – Replace control interface: If specific buttons never respond or the panel is erratic despite good connections, replace the control interface board / touch keypad assembly.
