Interior light does not turn on when the door is opened, but the unit cools normally.

Safety: Disconnect power before working on the light or door switch.

• Test door switch: Check if the display reacts to door opening (e.g., door icon). If not, suspect the door switch or reed sensor.
• Inspect LED module: Remove the light cover and check for visible damage. Ensure the connector is firmly attached.
• Replace LED module: Install a new Grundig LED light module if the old one is defective.
• Check wiring and PCB: If the LED and switch are good, the LED driver on the main PCB may be faulty and the board may need replacement.
