How to Fix / Troubleshooting
Safety first: Unplug the air fryer before any disassembly.
- Hard reset: Unplug the unit for 15–20 minutes. While unplugged, press and hold the main power/start button for 10 seconds to discharge residual power, then reconnect and test.
- Check for stuck buttons: Gently press each button on the control panel several times. If any button feels stuck or does not click, clean around it with a dry cloth. Do not use excessive liquid.
- Inspect control connections: Access the control panel and reseat the ribbon cable between the panel and the main board.
- Firmware/service mode: Some Breville models support a service reset sequence (consult the service manual). Perform the reset if available.
- Replace control assembly: If the error persists and no physical damage is visible, replace the control panel assembly or main control board as recommended by the parts documentation for your model.
