Interior light does not turn on when the door is opened, but the cooler otherwise operates normally.

Safety: Unplug the wine cooler before removing light covers or working on electrical parts.

Loss of interior lighting on a De Dietrich wine cooler is usually a simple electrical fault.

• Confirm settings: Some models allow the light to be disabled; check the user settings to ensure it is not turned off.
• Check door switch: Verify that the door switch is working by listening for a click or testing continuity when the door is opened and closed.
• Inspect LED module: Remove the light cover and check the LED for visible damage. Ensure the connector is firmly seated.
• Replace LED module: If the module appears damaged or does not light when powered, replace it with the correct De Dietrich LED assembly.
• Board driver: If a new LED does not work and the switch is good, the light driver on the main PCB may be faulty and the board may need replacement.
