Freezer interior light not working, but cooling is normal.

Safety first: Unplug the freezer before replacing any light components.

• Check door switch: Press the door switch manually. If the light does not come on, the switch or light circuit may be faulty.
• Inspect light module: Remove the light cover (usually clipped in). Check for obvious damage or discoloration.
• Replace light: Install a compatible De Dietrich LED light module or bulb as specified for your model.
• Check wiring: Ensure the light connector is firmly seated. If the new light still does not work, the control board's light output may be faulty.
