Safety first: Unplug the unit before removing light covers or accessing wiring.

Steps:

• 1. Inspect light module: Remove the interior light cover (usually clipped). Check for signs of moisture or burn marks on the LED board.
• 2. Check connections: Ensure the light module connector is firmly seated and wires are intact.
• 3. Test with door switch: Manually operate the door switch or magnet to see if the light responds.
• 4. Replace LED module: If the module is dark or flickering, install a new Liebherr LED light module.
• 5. If still faulty: The LED driver circuit on the main PCB may be defective and require professional replacement.
