JennAir Wall Oven Code 1d22: temperature sensing issue

What 1d22 means

JennAir built-in wall ovens such as the JJW2427DS and JJW8530DDS display 1d22 when there may be a problem with the oven temperature sensor, the control, or the wiring. This is the last of the 1d group in this family. The oven loses its trusted temperature reading, so it can stop heating or cut a cycle off early. Expect the preheat tone to stall or the cycle to drop out before it finishes.

Common causes of 1d22

Oven temperature sensor reading out of range
Oven control with a sensing problem
Wiring at the sensor damaged

✓ One safe check you can try

1. Cancel the cycle and leave the door ajar until the cavity cools. 2. Remove foil and loose pans from the oven floor and walls. 3. Switch the oven off at the breaker for two minutes. 4. If 1d22 returns when you bake, stop and phone us.

! Why to stop there

Replacing the sensor without testing the wiring can leave the code in place.
The oven's insulation hides the lead from view.
We confirm the cost in writing and warrant the repair 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.

1d221d22 questions

Why does my oven run hotter than set with 1d22 around?

A sensor reading wrong can make the control think the oven is cooler than it is. If you notice real temperature drift, stop using the oven and book a test.

Can 1d22 show only during preheat?

Yes. Preheat swings the temperature quickly, which exposes a weak sensor or a loose connection. The code may then seem to appear only at the start of a bake.

Is it a wiring problem if the sensor tests fine?

It can be. The official meaning includes the control and wiring, so we check each link before deciding what needs replacing. That way we avoid swapping a sensor that was never the real problem.
