Possible Causes

Burnt-out LED or bulb, Loose lamp wiring connector, Failed lamp driver circuit on main PCB

How to Fix / Troubleshooting

Safety: Unplug the fryer and allow it to cool before accessing the lamp area.

Steps to restore interior light:

  • Check settings: Ensure the light function is enabled if your model has a separate light button.
  • Access lamp: Remove the inner cover or lens over the light (usually inside the cooking chamber) or access from the rear depending on design.
  • Inspect lamp: Look for darkening or broken filaments (for bulbs) or burnt spots (for LED modules). Replace the lamp or LED module if defective.
  • Check wiring: Ensure the lamp connector is firmly attached to the main PCB or lamp driver board.
  • Driver issue: If a new lamp does not work, the lamp driver on the main control board may be faulty; replace the main control board if light function is important.

Note: Use only replacement lamps rated for high temperature and the correct voltage.
