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.
-
Do not force it 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 E126
What this one means
The latch is neither locked nor unlocked as far as the control can tell — E126 for the upper cavity, E226 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:
- E126, E226
- Three LEDs on the panel blinking out the digits 1, 2 and 6 — 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 latch motor stopped part way
- The latch microswitches
- The linkage binding
Worth doing before you call
- Let the oven cool completely and switch it off at the breaker for a minute
Then what
A latch caught between positions is the state that traps a door, so it is worth attending to before the next clean cycle rather than after.
