Oven light does not work but oven heats normally.

Safety first: Turn off power at the breaker before replacing the bulb to avoid electric shock.

• Replace bulb: Remove the glass lens cover inside the oven (usually twists off). Replace the bulb with the correct high-temperature oven lamp specified by Blomberg.
• Inspect socket: If the new bulb does not light, check the socket for corrosion or heat damage.
• Check door switch: Ensure the door switch is not stuck and that the light comes on when the door is opened (if designed to do so).
• Wiring and relay: If the socket and bulb are good, inspect wiring and the control relay for the light circuit. Replace the socket or control as needed.
