Microwave interior light does not come on when the door opens or during cooking, but unit heats normally.

Safety: Unplug the microwave before replacing the lamp. Avoid touching the new bulb glass with bare fingers.

Steps:

• 1. Access lamp: On many Avanti models, the lamp is accessible from the rear or top after removing a cover. Consult your manual.
• 2. Inspect and replace bulb: Remove the old bulb and inspect the filament. Replace with the correct wattage and type specified by Avanti.
• 3. Check socket and wiring: Ensure the socket is not burned or loose. Repair or replace if damaged.
• 4. Control board: If a known-good bulb does not light, the control board relay or wiring may be faulty and require professional service.
