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