Microwave interior light does not work, but the unit heats and otherwise operates normally.

Safety first: Unplug the microwave before replacing the lamp. Allow the lamp area to cool.

Step-by-step checks:

• 1. Locate lamp access: On many Paderno models, the lamp is accessible from behind a small panel inside the cavity or behind the control panel.
• 2. Remove cover: Unscrew the lamp cover and gently remove the bulb.
• 3. Inspect and replace: If the filament is broken or the bulb is darkened, replace it with the exact type and wattage specified in the manual.
• 4. Check socket: Ensure the socket contacts are clean and not burned.
