The microwave interior light is not working, but the unit heats and operates normally.

Safety first: Unplug the microwave before replacing the lamp. Do not touch high-voltage components.

• Step 1 – Access lamp: On many AEG models, the lamp is accessible from the rear or side by removing a small cover plate. Consult the user's manual.
• Step 2 – Replace bulb: Remove the old lamp and install a new AEG-specified microwave lamp of the correct wattage and type (usually a special high-temperature bulb).
• Step 3 – Check connections: Ensure the lamp holder contacts are clean and tight. Refit the cover securely.
