Interior lights not working but refrigerator cools normally.

Safety: Unplug the refrigerator before replacing light modules.

Steps:

• Check door switch: Press the switch manually; if the display responds but lights do not, suspect the LED module.
• Inspect LED module: Remove the light cover and check for burn marks.
• Replace LED: Install a Miele‑approved LED module, matching connectors.

If multiple modules are out, the LED driver on the control board may be faulty and requires professional service.
