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 door locked shut
					A self-clean cycle that has finished and a door that will not open. The latch releases on temperature rather than on a timer, and forcing a professional door turns a small repair into a large one.

														Door locked after a clean cycle

														Self-clean that will not start at all

														A latch code in the hundreds

## About Thermador oven error code E124

### What this one means

The door switch is in a state the control cannot make sense of — neither properly open nor properly closed — E124 for the upper cavity, E224 for the lower one. 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:

- **E124, E224**
- **Three LEDs on the panel blinking out the digits 1, 2 and 4** — 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 door switch
- A door that is not closing squarely on its hinges
- The harness to the control module

### What to try yourself

- Close the door firmly and watch the oven light — it should go out
- Look along the seal for a gap at one corner, which usually means a hinge rather than a switch

### Then what

The interior light is the free test here: a light that stays on with the door shut is a switch the control also cannot read. Hinges sag on heavy Professional doors, and that is a different repair from the switch.
