KitchenAid Wall Oven Code 1d22: Temperature input from the sensor lost

What 1d22 means

On KitchenAid wall ovens and combination wall ovens, 1d22 reports a possible problem with the oven temperature sensor, the control, or the wiring. The control no longer trusts the temperature information it receives, so the oven halts heating. The code stays on the display until the cause is addressed or cleared. Heating stops entirely. Food is simply left unheated, and the preheat tone never sounds.

Common causes of 1d22

Oven temperature sensor giving an unreliable reading
Oven control that fails to read it
Wiring that is loose or burnt near the sensor

✓ One safe check you can try

1. Press Cancel and let the oven cool down. 2. Reset the breaker for about a minute. 3. Try a low bake to see if the code comes back. 4. If 1d22 returns, leave the oven off and call. 5. Write down the display.
