Symptom
Thermador oven smoking or smelling
Smoke during a bake, a burning smell on first use, or an odor that has appeared since the last clean cycle. Most of it is what is in the oven rather than the oven itself.

Five ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
Spills on the cavity floor
The overwhelming majority. Sugar and fat left from a previous bake smoke long before anything is wrong with the appliance.
-
A new oven burning off
Manufacturing residue on elements and insulation. Unpleasant, expected, and gone after a couple of hot empty runs with the room ventilated.
-
Self-clean residue
Ash left in the cavity after a clean cycle smells on the next bake. Wipe it out once it is cold — the cycle turns soil to ash, it does not remove it.
-
A cooling fan that is not keeping up
Published as its own condition. Heat that should be leaving the cabinet is not, and the smell is the cabinetry rather than the food.

An element or relay staying powered
The serious one, and the one the safety condition is watching for. It is why the code matters more than the smell.

01
Look at the cavity floor cold
And under the racks. Nine times in ten the answer is there.
-
02
Wipe out after any clean cycle
Ash is what a self-clean leaves behind, and it is what smells on the next bake.
-
03
Note whether there is a code
Smoke with an over-temperature or fan condition is not the same page as smoke with no code, and it changes the urgency completely.
-
04
Ventilate and run empty
For a new appliance: two hot empty runs with the hood on. If the smell persists after that, it is worth a call.
How it shows up
What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.

About Thermador oven smoking or smelling
First: is anything overheating that should not be
Smoke with a code for cavity over-temperature or cooling fan supervision is a different situation from smoke with no code at all. If the oven is heating with nothing selected, switch it off at the breaker and call rather than working through this list.
Most of it is not the oven
Spills on the cavity floor, ash left after a clean cycle, and the burn-off on a new appliance account for nearly all of these calls. All three are ordinary and all three are free to deal with. What separates them from the rest is that they get better rather than worse, and none of them comes with a code.
The two that are the appliance
A cooling fan that is no longer moving enough air, and an element or relay that stays powered. The first is published as a condition, the second is what the over-temperature condition exists to catch. Either of those turns a smell into something to act on the same day.

Questions about thermador oven smoking or smelling
My new oven smells like burning plastic.
Usually the burn-off of manufacturing residue on the elements and insulation, and it goes after a couple of hot empty runs with the room ventilated. If it is still there after that, stop and call.
It smokes every time now, even when clean.
Then it is worth looking at the appliance rather than the food — a cooling fan condition, or an element staying powered. Check for a code first, because that is what separates the two.
Is a smell of gas the same thing?
No. That is not a symptom to work through: shut the gas off, ventilate, and call. Nothing on this page applies to it.
