Oven light does not turn on when the door is opened or when the light button is pressed.

Safety first: Disconnect power before replacing the bulb.

Steps:

• Remove the glass light cover inside the oven and inspect the bulb. Replace with a Tecnogas-compatible high-temperature oven lamp.
• If the new bulb does not work, check the door switch by pressing it manually; listen for a click and test continuity with a meter.
• Inspect the lamp socket and wiring for burns or loose connections.

If the switch and wiring are good, the control board light relay may be faulty.
