Oven interior light doesn't work

A dead oven light is usually just a burned-out bulb, though the bulb type must be an appliance-rated bulb able to withstand oven heat, not a standard household bulb.

Symptoms

  • Light doesn't turn on when the door opens or the light switch is pressed
  • Light flickers before going dark
  • Bulb looks visibly blackened
  • Everything else about the oven works fine

Likely causes

  • CommonBurned-out oven light bulbOven bulbs are rated for high heat but still burn out like any bulb over time.
  • CommonBulb not properly seated in the socketVibration or a recent bulb change can leave it loosely seated.
  • PossibleFaulty light switchThe door-activated or panel switch that controls the light can fail separately from the bulb.
  • Less commonWiring issue at the socketA loose or damaged wire at the socket can prevent power from reaching a good bulb.

What to do

  1. Turn off and unplug the oven, or shut off its breaker, before replacing the bulb.
  2. Locate the light cover, usually a small glass or plastic dome inside the oven cavity, and remove it per your model's instructions.
  3. Unscrew the old bulb and check for blackening or a broken filament.
  4. Install a new bulb rated specifically for oven use (typically 40W appliance bulb), not a regular household bulb.
  5. Reinstall the cover and restore power to test.
  6. If a new bulb doesn't light, check that it's screwed in fully and try reseating it.
  7. If the socket and bulb both seem fine but the light still doesn't work, have a technician check the light switch and wiring.
