The short answer
E12 means the control has lost confidence in the gas sensor or its wiring. Because every safe-operation decision downstream depends on this circuit, the appliance locks out - and it should stay locked out until a technician has cleared it.
This code and its neighbours on this appliance
Reference| Code | Meaning |
|---|---|
| E12 | There is a problem with the Gas Sensor or the associated wiring. |
| E11 | The Gas Sensor reported a problem to the control board. There may be a problem with the Gas Sensor or the associated wiring. |
| E13 | The oven did not pre-heat correctly. There may a problem with the Appliance Control Board or the associated wiring. |
What you see alongside the code
- Other functions on the oven still work — Electric elements and the control panel are often unaffected, which can hide how serious this is.
- A smell of gas with or without the code — Stop. Leave the building and call the gas utility from outside - the code is irrelevant at that point.
- NEAR MISS - the burner lights and runs normally — If the oven is running gas normally and the code is displayed, it still needs attention rather than dismissal.
What triggers it, most likely first
- A failed sensing element — The part the code names. It is a wear item in a hot, corrosive position, and it is the most common single cause.
- A connector or harness fault at the sensor — The run sits in the heat of the burner compartment where insulation hardens and pins corrode.
- Contamination on the sensor — Combustion residue on the element changes what it reports.
Check in this order, and why
- Confirm there is no smell of gas before anything else — Nothing on this list matters until that is settled, and settling it means leaving the building, not investigating.
- Shut off the gas supply to the oven — The correct holding state while the fault stands.
- Note whether the code appears before or after an ignition attempt — Before means a circuit check; after means the control saw something during combustion.
The owner-safe procedure
- If you smell gas, do not switch anything on or off — If you smell gas: do not switch anything on or off, leave the building, and call the gas utility or 911 from outside.
- Shut off the gas supply valve to the oven — A quarter turn at the shutoff behind or beneath the appliance.
About 5 min
- Record the exact code and when it appears — Before ignition or during it. That timing is what a technician will ask for first.

Safety
If you smell gas: do not switch anything on or off, leave the building, and call the gas utility or 911 from outside. Do not look for the leak yourself. Separately, and only where there is no smell of gas: unplug the appliance or switch off its breaker before removing any panel - a capacitor can hold a charge after the power is off. Never defeat, bypass or jumper a gas sensing circuit to get the oven to light.
When this is a service call
Call a technician now. There is no owner-side check on a gas sensing fault, and there is no reset that makes the oven safe to use while it stands. Shut the gas supply valve to the appliance while you wait. If you smell gas at any point, leave the building and call the gas utility or 911 from outside instead - that call comes before every other consideration.

What this page does not cover
Read this as generalized information. It is written for E12 as the KitchenAid oven code list documents it across the brand rather than for one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer and is linked from the code index for this appliance. Some of the codes listed beside it in the table above carry the same documented meaning on this platform and some are documented differently, so check the characters on your display carefully before acting on this page.
