KitchenAid Range Code 1d12: Temperature sensor circuit

What 1d12 means

A KitchenAid range showing 1d12 reports that the oven temperature sensor, the control, or the wiring that links them may have a problem. It is the sister of 1d11 in the 1d group, and no model number is tied to it. Common signs are an oven that does not reach temperature or a display that shows the code when bake is pressed.

Common causes of 1d12

Oven sensor with a wrong reading
Control interpreting the sensor signal
Connection between sensor and control

✓ One safe check you can try

1. Turn off the oven and let it cool. 2. Look inside, without touching, to see the thin sensor probe; make sure nothing rests against it. 3. Switch the breaker off for 60 seconds and back on. 4. Start a short bake. 5. If 1d12 shows again, stop and call us.

! Why to stop there

Measuring sensor resistance takes a meter and the right chart.
Owners cannot see the wiring path to the control.
We give a written quote first with a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

1d121d12 questions

What does the sensor do?

It tells the oven control the cavity temperature so the heating element can be switched on and off at the right moments. Without a good reading, the oven cannot hold temperature.

Why would the oven overheat or underheat?

A sensor or control that reads wrongly can make the oven heat too long or too little. That is why the code stops normal use until the circuit has been tested.

Will cleaning the oven help?

Cleaning does not fix this code. Avoid spraying cleaner near the sensor probe, and call us if the code returns after you have cleaned and reset power.
