Interior light not working but refrigerator otherwise cools normally.

Safety: Disconnect power before replacing light modules or working near wiring.

Steps:

• 1. Check door switch: Press the door switch manually. If the display responds but the light does not, the switch is likely good and the light module is suspect.
• 2. Inspect light module: Remove the light cover (usually clipped into the ceiling or side wall). Check for discoloration or burn marks.
• 3. Replace light module: Install a new Gaggenau-compatible LED light module or bulb. Ensure connectors are firmly seated.
• 4. Test: Restore power and open the door to confirm operation.

Note: If multiple lights fail simultaneously, the light driver circuit on the main control board may be defective and require professional replacement.
