KitchenAid Wall Oven Code 3d12: Temperature sensor path flagged

What 3d12 means

A KitchenAid wall oven or combination wall oven showing 3d12 may have a problem with the oven temperature sensor, the control, or the wiring. It is the companion of 3d11 in the same lower-case family. Owners see the code replace the clock, and the oven stays cold or stops soon after it begins to heat. The oven may stop soon after it starts.

Common causes of 3d12

Oven temperature sensor out of its normal range
Control that cannot interpret the sensor signal
Loose or damaged wiring on the sensor path

✓ One safe check you can try

1. Press Cancel and let the oven rest with the door closed. 2. Take the oven off its breaker for a minute. 3. Try a short low-temperature bake. 4. If 3d12 shows up again, call us rather than repeating the test.
