KitchenAid Range Code 3d12: Oven sensor circuit notice

What 3d12 means

KitchenAid range code 3d12 advises of a possible problem with the oven temperature sensor, the control, or the associated wiring. It follows 3d11 and carries the same message, and no model number goes with it. The display holds the code while the oven may heat unevenly, take too long to preheat or not heat at all. Write down the exact digits before phoning, since 3d11 reads almost the same.

Common causes of 3d12

Temperature sensor giving a wrong signal
Control reading the sensor
Wiring along the sensor path

✓ One safe check you can try

1. Cancel what the oven is doing. 2. Allow it to cool. 3. Look for anything pressed against the sensor probe and remove it. 4. Take power away at the breaker for a full minute, then restore it. 5. Try a brief bake; call us if 3d12 reappears.

! Why to stop there

Only a meter shows whether the sensor, board or wiring is the source.
Repeat resets can hide a getting-worse sensor.
The price is put in writing before we begin, and labor is warranted for 30 days.

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.

3d123d12 questions

Do 3d11 and 3d12 need separate repairs?

They name the same areas, so one visit covers the testing for both codes. If a part needs replacing, we explain it and quote the price in writing first.

Can a power cut cause this?

A power event can upset a control, so one reset is a fair first step. The code names the sensor circuit, so a repeat still needs testing by a technician.

Is the oven dangerous with this code?

Not suddenly, but unreliable heat spoils food and puts stress on parts. Leave the oven off until the sensor, control and wiring have been checked.
