On a double oven the code tells you which cavity before anyone opens anything. - **From $95** diagnostic, credited to the repair - **59** cities and neighborhoods covered - **OEM** parts available on order - **In writing** the price, before anything is opened ## Book a diagnostic visit Your model number and a line about what it is doing is enough to get started. Your details stay private. No spam, ever. 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. - The cavity temperature sensor Reading open, so the control has no temperature to work from and will not heat.

In five minutes ## Before you call anybody None of it needs tools, and all of it makes the visit shorter. - 01 Which cavity, and does the other work? Write it down before you call. It halves the diagnosis and it changes what we bring. ### Which cavity, and does the other work? Write it down before you call.

How it shows up ## What people describe when they call - “Sets a temperature and stays cold” - “One cavity works, the other does not” - “A code beginning E1 or E3” Two shortcuts ## Narrow it down before anybody arrives A description of the behaviour leaves a few possible causes. A code names the subsystem, and the model number says which parts to bring. Either one shortens the visit; both together usually settle it.

If only one cavity has stopped, this is one repair rather than two — and the working cavity proves the controls and the supply are alive. ### The cavity is in the number Double and triple ovens on this make publish paired codes: E101 and E201 are the same condition in the upper and lower cavity, and so are E104/E204, E115/E215 and E118/E218. Before anyone opens anything, the number has already told you which oven you are talking about — and whether the one you actually use is affected. ### Sensor or element They fail differently and the symptom tells you which. A sensor reading open leaves the control with no temperature at all, so it will not heat; an element that has failed open still lets the oven warm slowly or unevenly, usually from one direction. Both are ordinary repairs, and the code narrows it before a technician arrives. This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about thermador oven not heating Then the code will begin E1 and the lower cavity is untouched. They share a control module but not their elements or sensors, so this is normally a single contained repair. The panel runs on a different supply from the elements. On a double oven fed by two legs, losing one leaves the display perfectly happy and the oven cold — which is why the breaker gets checked properly rather than looked at. That is a mismatched module: a new board that has not been told which model it is in. It is set from the data plate in service mode, and it is the whole repair.
