What we can confirm

## Code E012, from the manufacturer’s own documentation

A code is only meaningful together with the generation showing it — the same two digits mean different things across generations.

What it looks like from the kitchen

## The symptom this code usually arrives with

A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.

- Oven controls not responding
					A touch panel that ignores you, repeats itself, or reports a key held down. On a panel above a cooktop the usual cause is condensation, and it clears when the panel dries.

														Panel unresponsive or erratic

														A code about a key being held

														Dead panel with no lights at all

## About Thermador oven error code E012

### What this one means

The temperature sensor built into the user interface board is reading wrongly. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.

### The other ways your machine may say it

The same condition is published under more than one label, because it has been carried across generations of this appliance:

- **Three LEDs on the panel blinking out the digits 0, 1 and 2** — how a model with no digital display says it. On that machine, the lights are the code

### What the code covers

A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:

- The user interface board, which carries the sensor

### Worth doing before you call

- Note whether it appears cold or only after a long bake — it helps separate a sensor from real overheating

### Then what

This is the board’s own sensor, not the oven’s, so it says nothing about how hot the cavity is getting. It is read together with E003, which is the panel genuinely running hot.

This code is published for wall ovens & steam ovens. The [full list of codes](https://thermadormiami.support/error-codes/) has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
