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

Safety first: Disconnect power before replacing bulbs or sockets.

• Replace bulb: Remove the oven light cover and replace the bulb with the correct type and wattage specified by Bosch.
• Check socket: If a new bulb does not work, inspect the light socket for corrosion or heat damage and replace if necessary.
• Test door switch: Ensure the door switch is operating correctly; the light should turn on when the door opens.
• Control relay: If all hardware is good, the control board light relay may be faulty.
