Switch the oven off at the breaker first, not just at the panel. A halogen capsule in particular will fail quickly if it has been touched. ### Why the wrong bulb matters more than it sounds An oven bulb lives at cooking temperature inside a sealed housing and gets knocked every time the door closes. Appliance bulbs are built for that. A household bulb put in because it fitted will fail in weeks, and when it fails hot it can seize in the socket or break, which turns a two-minute job into a real one. It is the commonest reason we see a socket that has cooked. ### The door switch, which is worth knowing about The same switch that controls the light often tells the oven other things — whether it is safe to run a clean cycle, whether the cooling fan should be on. A worn one usually shows itself first as a light that behaves oddly, which makes this small complaint an early warning worth mentioning rather than ignoring. By a long way the usual answer, and the one thing on this page an owner can reasonably do. The wrong bulb fitted last time A household bulb in an oven socket fails within weeks, and it can shatter or seize in the fitting. This is why a light that keeps going is worth mentioning. The door switch It tells the oven the door has opened. A worn switch leaves the light off with the door open, and on some ovens leaves it on with the door shut — which is the version worth fixing quickly. The socket or its wiring A socket that has run hot for years, usually because of the wrong bulb. Cheap, but it is a part rather than a bulb change. The control, on ovens where the light is switched electronically Rare, and only after everything above. Try the light button with the door shut On ovens that have one. Working with the door closed and not with it open is the door switch. Look at the bulb Blackening or a broken filament is visible. So is a bulb that is not an appliance bulb. Breaker off before touching anything The oven panel is not enough. This is a live socket inside a metal box. Handle a new bulb with a cloth Especially a halogen capsule. Finger oil is why the last one failed early. Small, and worth doing properly What it usually means Dark cavity with everything else working A light that flickers or works only when cold A bulb replaced recently that has already gone The fastest diagnosis is what you can see If you replace the bulb yourself, use an appliance bulb rated for oven temperatures and handle it through a cloth — oil from fingers creates a hot spot on the glass and shortens its life dramatically.

A worn one usually shows itself first as a light that behaves oddly, which makes this small complaint an early warning worth mentioning rather than ignoring. ### My light will not stay on for more than a few weeks. Almost always the wrong bulb. Oven bulbs are built for the temperature and for the vibration of a door being closed; a household bulb is not, and it will fail repeatedly. The second possibility is a socket that has been overheated by exactly that, which is a small repair rather than another bulb. ### The light stays on with the door closed. That is the door switch, and it is worth fixing sooner rather than later. A bulb burning constantly in a hot cavity fails fast and the heat it adds is not helping anything around it. ### Is it worth calling someone out for a light? On its own, honestly, often not — and we would rather say so. It is a good thing to add to a visit for something else, or to a maintenance call. If the bulb has been changed and it still does not work, that is different: then it is a switch or a socket and it does need somebody. --- **[Read full article: Oven light not working](https://bertazzonimiami.support/symptoms/oven-light-not-working/)**
