Error code

# Thermador oven error code E101

Thermador error code E101: the temperature sensor in the oven cavity reads as an open circuit, so the control has no temperature to work from — E101 for the upper cavity, E201 for the lower one on a double or triple oven. What the code covers, what to check first, and what it does not tell you — on wall ovens & steam ovens.

## Code E101, 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 not heating
					An oven that lights up, sets a temperature and never gets there — or does nothing at all. On a double oven the code tells you which cavity before anyone opens anything.

														Sets a temperature and stays cold

														One cavity works, the other does not

														A code beginning E1 or E3

## About Thermador oven error code E101

### What this one means

The temperature sensor in the oven cavity reads as an open circuit, so the control has no temperature to work from — E101 for the upper cavity, E201 for the lower one on a double or triple oven. 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 two labels are the two cavities of a double or triple oven, not two ages of machine — E1xx is the upper cavity and E2xx the lower, and the number tells you which one to look at:

- **E101, E201**
- **Three LEDs on the panel blinking out the digits 1, 0 and 1** — 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 cavity temperature sensor
- The harness from the sensor back to the control module
- The plug at the control module

### Worth doing before you call

- Note which cavity shows it — on a double oven the number tells you, and the other cavity often still bakes normally

### Then what

A sensor that reads open is a part, and it is reached from inside the cavity. The useful thing about this code is that it names the circuit rather than the component, so the harness is tested before the sensor is condemned.

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.
