Possible Causes

Failed LED/LCD display driver, Loose display connector, Shorted display backlight, Firmware corruption on main PCB

How to Fix / Troubleshooting

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

  • Power reset: Leave unplugged for 10 minutes, then reconnect. If the fan or heater starts without a visible display, unplug immediately.
  • Inspect display connection: Remove the front panel and check the connector between the display board and main PCB. Reseat it firmly.
  • Check for damage: Look for burnt or cracked components on the display board.

Because running without a visible display is unsafe, replace the display module or entire control panel assembly. If the main PCB is driving outputs without proper control, it should also be replaced.
