Display works but temperature or time cannot be adjusted, or buttons respond intermittently.

Safety first: Unplug the air fryer before cleaning or opening the control panel.

• Clean the panel: Wipe the control surface with a soft cloth lightly dampened with mild detergent. Do not spray cleaner directly onto the panel.
• Drying time: If the panel was exposed to liquid, leave the unit unplugged for 24 hours to allow internal moisture to evaporate.
• Check ribbon cable: Remove the front fascia and ensure the touch panel ribbon is firmly seated in the PCB connector.
• Test all keys: After reassembly, test each button. If specific keys remain unresponsive, the touch panel assembly likely needs replacement.

Do not press the panel with sharp objects; this can permanently damage the touch membrane.
