Oven light not working, all other functions normal

Safety first: Switch off power to the oven before changing the lamp to avoid electric shock.

• Replace the bulb: Remove the glass lamp cover inside the cavity (usually twists off). Replace the bulb with the correct high‑temperature oven lamp specified for your Etna model (typically 25W or 40W, E14 base).
• Check lamp holder: If a new bulb does not work, inspect the lamp holder for heat damage or corrosion. Replace the lamp holder assembly if contacts are burned.
• Inspect wiring: From the rear, trace the lamp wires back to the PCB. Repair any damaged insulation or loose connectors.
• Control issue: If the lamp never turns on even when commanded from the control panel, the lamp relay/triac on the main PCB may have failed. Replace the main PCB if no voltage is supplied to the lamp during operation.
