Microwave interior light does not come on, but heating and other functions work normally.

Safety first: Unplug the microwave before replacing the lamp. Some models require removal of the outer cover.

• Access lamp: On many Miele models, the lamp is accessible from the rear or side behind a small cover. Remove screws and cover.
• Replace bulb: Install a new lamp of the exact type and wattage specified by Miele (often a special high-temperature appliance bulb).
• Check socket: Ensure the lamp is seated firmly and the socket contacts are not corroded.
• Test operation: Restore power and open the door to verify the light works.
