What the display is telling you
The brand reads 1d12 as an oven temperature sensor, control or wiring fault. The oven may refuse to heat, overshoot, or bake unevenly; after one power-down reset, the next step is a resistance test of the sensor, which is technician work.
Error codes
Reference| Code | Meaning |
|---|---|
| 1d12 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
What you notice alongside 1d12
- The code appears at power-up — The control checks the sensor circuit straight away.
- The code appears partway through a bake — A fault that shows only as the sensor or its wiring warms.
- The code followed a self-clean — High heat is hard on the sensor wiring behind the cavity.
- NEAR MISS: the oven is slightly off its setting, with no code — A small, steady difference is a calibration matter that the use-and-care guide covers.
What triggers 1d12, ranked
- Temperature sensor failed — The likeliest cause here: the sensor itself, the part a meter test checks first.
- Sensor connector or wiring — Next: the connector behind the back wall of the cavity browns and loosens in the heat, giving an on-off reading.
- Control misreading the sensor — Third: the control, which can misread a healthy sensor.
- Probe bent or touching the oven wall — Least likely: a probe knocked by a rack or a pan reads the wall instead of the air, which throws the reading.
Diagnostic order
- Check with an oven thermometer — A thermometer on the middle rack shows whether the oven runs hot or cold.
- Note when the code appears — At power-up, during preheat or partway through a bake.
- Recall recent self-cleans or repairs — Both stress the sensor wiring.
- Stay with the oven while it heats — Do not leave it running alone while the reading is in doubt.
Reset and owner-safe checks
- Power-down reset — Switch off the breaker for a minute, then restore power.
About 2 min
- Plain bake test — Run a plain bake and stay nearby, noting whether and when the code returns.
About 20 min
- Keep a short log — Note the code, when it appeared, and any recent self-clean or repair.
Tools: notepad or phoneAbout 2 min
- STOP before removing the sensor or the back panel — The sensor connector sits behind the cavity wall; disconnecting and testing it is technician work.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. With the breaker off, press a key to confirm the display stays dark before you touch anything behind a panel.
When a reset is not enough
Book a test once a reset fails to clear the code. The sensor is a common, modest part, but the wiring and the control produce the same code, and a meter decides which one it is.

Generalized information
This is generalized information: it reads 1d12 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 1d12 exists yet; when one does, it is the more specific answer for that model line.
