How to Fix / Troubleshooting

Safety first: Unplug the air fryer before removing any covers.

  • Dry the panel: If the panel was recently cleaned or exposed to steam, unplug the unit and let it dry for several hours. Do not use hairdryers or heat guns.
  • Clean surface: Wipe the touch panel with a soft, dry cloth to remove grease or residue that may interfere with touch sensing.
  • Check cable connection (advanced):
    • Remove the front/control panel cover.
    • Locate the flat ribbon cable from the touch panel to the control board.
    • Reseat the cable and ensure there is no corrosion or damage.
  • Panel replacement: If certain buttons never respond or E9 persists, the touch panel assembly may need replacement. This is usually a plug-in part but requires careful disassembly.
