Possible Causes

Burned-out oven light bulb, Faulty light socket, Failed light switch or relay on control board

How to Fix / Troubleshooting

Safety: Turn off power or at least ensure the light switch is off and the bulb is cool before handling.

  • Replace bulb: Remove the light cover (usually by twisting) and replace the bulb with the correct high-temperature oven bulb.
  • Check socket: If a new bulb does not work, inspect the socket for corrosion or burning. Replace the socket if damaged.
  • Test voltage: With power on and light commanded on, carefully test for voltage at the socket. If no voltage, the light relay or control board may be faulty.
  • Replace control: If the control is not sending power to a good socket and bulb, replace the EOC or light relay board (if separate).
