The short answer
E12 says there is a problem with the gas sensor or its wiring. The brand’s list does not describe the sensor further, and its location depends on the model; the code concerns the sensor’s own circuit, so the owner side ends at a reset.
Error codes
Reference| Code | Meaning |
|---|---|
| E12 | There is a problem with the Gas Sensor or the associated wiring. |
What the oven does with the code showing
- A function stops or will not start — The control may refuse a function that relies on the sensor.
- The code returns after a reset — A real sensor or wiring fault.
- The code followed cleaning near the vents — Moisture or cleaner reaching the sensor area.
- NEAR MISS: a smell of gas — That is not this code; leave the building and call from outside.
Likely causes, in order
- Gas sensor failed — Most likely: the sensor, once a reset has been tried.
- Wiring or connector to the sensor — Second: a loose or damaged connector between the sensor and the control.
- Moisture or residue at the sensor — Third: residue or moisture near the sensor.
- Control fault — Least likely: the control misreads a healthy sensor.
Where to start, and what comes next
- Power-down reset — Breaker off for a minute, then on.
- Note when the code appears — At power-up, or with a particular function.
- Recall cleaning or repairs — Moisture or a disturbed connector are both common.
- Technician tests the sensor and wiring — With the power off.
What you can safely do
- Power-down reset — Switch off the breaker for a minute, then restore power.
About 2 min
- Avoid the function that triggers it — If one function brings the code back, use others until the repair.
About 1 min
- Record the code — Note the code exactly, when it appeared and what was running.
Tools: notepad or phoneAbout 2 min
- STOP before opening panels — The sensor and its wiring sit behind panels; testing them is technician work.
Power off before any panel
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 oven cool fully first: the elements, the door glass and the vent area stay hot long after the display goes dark. If you smell gas, do not switch anything on or off, leave the building, and call the gas utility or emergency services from outside.
The point to call
Call when the code returns after a reset. If you smell gas at any time, leave the building and call the gas utility or emergency services from outside; that comes before any appliance repair.

Generalized information
This is generalized information: it reads E12 the way Amana documents it for Amana ranges and wall ovens whose electronic control reports codes in this form. It does not apply to Amana models with knob-only controls, Amana cooktops sold as separate units, which keep their own list, or sister brands on the same platform, whose lists can read differently. No model-specific page for E12 exists yet; when one does, it is the more specific answer for that model line.
