Oven Light Not Working — How to Replace the Bulb
When the oven light goes out, it is nearly always just a burnt-out bulb — an easy, cheap swap. You just need the right type of bulb, because oven bulbs are special high-heat units.
Get the Right Bulb
Oven bulbs are special appliance bulbs rated for high heat (usually a 40W appliance bulb, often G9, halogen, or a screw-in type depending on model). A regular household bulb will not survive oven temperatures. Check your manual or the old bulb for the type, commonly a 40-watt appliance/oven bulb.
Replace It Safely
Make sure the oven is cool and unplug it (or shut the breaker). Most oven bulbs are behind a glass cover inside the oven — twist or pop the cover off, unscrew or pull out the old bulb, and install the new one. Wear a glove or use a cloth so skin oils don't shorten a halogen bulb's life. Replace the cover and restore power.
If a New Bulb Doesn't Work
If a fresh, correct bulb still doesn't light, the issue is the light socket, the switch, or wiring — less common, but a moderate repair. Confirm you bought a working high-heat bulb of the right type first.
