Safety: Switch off power before changing the bulb. Use only oven-rated bulbs.

Replace bulb: Remove the glass cover over the lamp (usually by twisting) and replace the bulb with the same type and wattage.
Check holder: Inspect the lamp holder for heat damage or corrosion. Clean contacts if lightly oxidized.
Test switch: If the bulb and holder are good, test the oven light switch or control output for continuity and voltage.
Replace holder or switch: Install a new lamp holder or light switch if they are defective.

Etna oven light does not work, but oven heats normally.
