The short answer
1d11 names the oven temperature sensor, the control, or the wiring between them. The sensor is a resistance probe in the cavity wall and it is the only thing telling the control how hot the oven actually is, so when its reading goes out of range the control stops trusting the cycle rather than guessing.

What you observe, and what to record
- The oven runs hot, runs cold, or will not settle — A drifting probe produces cooking that is wrong in a consistent direction before it produces a code.
- Whether the display shows anything besides the code — A second code, a flashing indicator or a missing segment is information the code number alone does not carry.
- Whether the ${A} still does everything else it should — What still works narrows the search as effectively as what does not, and it is the question a technician asks first.
Causes, most likely first on this oven
- The sensor itself has drifted or opened — First: it is a resistance probe that spends its life at cooking temperature, and drift is its ordinary end rather than a sudden failure.
- A connector fault at the back of the cavity — Second, and genuinely common — the sensor plugs in behind the rear wall, and a connector that has relaxed reads as an open probe.
- Chafed wiring on the sensor lead — Third: the lead runs close to the cavity, and where insulation has worn through to the shell the reading collapses.
Check in this order, and why
- Note whether the oven is hot or cold when the code appears — An open circuit reads the same from cold; drift only shows at temperature. The timing splits them.
- Compare the display against an oven thermometer — A consistent offset is drift; wild swings are wiring.
- Check whether the code follows one cavity on a double oven — Each cavity has its own probe, and that narrows the search immediately.
What an owner can safely check
- Power the oven down at the breaker and restore it — Clears a latched code so you can watch how quickly it returns.
About 5 min
- Photograph the display with the code showing — Codes are easy to transcribe wrongly and a photograph is not. It also timestamps the fault, which matters if it becomes intermittent.
About 5 min
- Check the breaker for the appliance, fully off and on — A breaker that has tripped partway does not look tripped. A definite off, then on.
About 5 min
- STOP HERE — the sensor connector is inside the cabinet — It is reached through the rear, on the live side.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Let the cavity cool completely first: the racks, the door glass and the trim all hold heat for far longer than the display suggests, and the lock will not release above its own threshold anyway.
When to call a technician
Call once the code returns after a reset, or once the thermometer shows an offset you would not cook around. A technician meters the probe cold against its published resistance and can usually settle sensor-versus-control in a single visit; the sensor itself is one of the more affordable parts in the appliance.

What this page does not cover
This page reads 1d11 for Jenn-Air ovens in general, from the manufacturer's shared code index. A code can be documented differently for one family, so where a model-line page exists for your unit it is the more specific answer and is linked below. Not here: wiring colours, connector positions and part numbers, which differ by family.
