Microwave shows E17 and the interior light flickers or fails.

Safety: Unplug the microwave. The lamp area may be hot if recently used.

Steps:

• 1. Access lamp: On many Sharp models, the lamp is accessible via a small cover on the side or top of the cabinet. Remove the cover screws to access the bulb.
• 2. Inspect bulb: Check if the filament is broken or the bulb is darkened. Replace with the exact type and wattage specified by Sharp.
• 3. Check socket and wiring: Ensure the lamp is seated firmly in the socket and that wires are not loose or burnt.

Advanced: If a new bulb does not restore operation and E17 remains, the lamp relay or control board circuit may be faulty and require professional diagnosis.
