3d11 in brief
3d11 says the control cannot trust the temperature reading it is getting. Until that is fixed the oven may heat too much, too little or not at all, so do not leave it baking unattended.
Error codes
Reference| Code | Meaning |
|---|---|
| 3d11 | There may be a problem with the Oven Temperature Sensor, the Control, or the associated wiring. |
Signs that go with the code
- 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.
- The probe inside the oven looks bent or loose — A probe touching the wall reads the wall, not the air.
- 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.
Causes, most likely first
- Temperature sensor failed — Most likely: the probe’s resistance drifts out of range or opens with age and heat, and the control stops trusting it.
- Sensor connector or wiring — Second: a heat-damaged connector or wire between the probe and the control.
- Control misreading the sensor — Then: the control’s sensing circuit fails, so a good sensor reads wrong.
- Probe bent or touching the oven wall — Last: a displaced probe, which an owner can see without tools.
The order to check, and why
- Power-down reset — Breaker off for a minute, then try a plain bake.
- 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.
Owner steps, with tools and time
- Power-down reset — Switch off the breaker for a minute, then restore power.
About 2 min
- Inspect the probe — With the oven off and cool, look at the probe at the back of the cavity and move racks so they do not touch it.
Tools: flashlightAbout 3 min
- Thermometer check — Place an oven thermometer on the middle rack, preheat, and compare its reading with the setting.
Tools: oven thermometerAbout 25 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.
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. A wall oven is heavy and hangs on its trim and screws; taking it out of the cabinet is a two-person job, not an owner check.
When this is a service call
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 3d11 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 3d11 exists yet; when one does, it is the more specific answer for that model line.
