Buttons beep but settings do not change or temperature/time cannot be adjusted.

Safety first: Unplug the air fryer before removing the control panel.

• Clean panel surface: Remove any sticky residue or spills that may cause keys to stick.
• Reset control: Unplug for 5–10 minutes to reset the UI firmware.
• Check for stuck keys: Gently press each button to ensure it moves freely. If a key feels stuck, the touch overlay may need replacement.
• Inspect encoder: For models with a knob, remove the knob and check the encoder shaft for damage. Replace the encoder if it skips or does not register turns.
• Replace UI board: If beeps occur but settings never change, replace the user interface board.
