JennAir Wall Oven Code 1c31: oven control or wiring problem

What 1c31 means

On JennAir built-in wall ovens, such as the JJW2830LL and JJW2427DS, the code 1c31 means there may be a problem with the oven control or the wiring connected to it. The control is the board that runs the heating and the cycle logic. You will see 1c31 on the display, and the oven may stop heating or refuse to start.

Common causes of 1c31

Oven control board reporting an internal problem
Wiring to the control loose or damaged

✓ One safe check you can try

1. Tap Cancel and give the oven a full minute to settle. 2. Turn the oven's breaker off for two minutes and then restore power. 3. Watch that the display lights up and the clock can be set. 4. If 1c31 shows again, do not keep resetting the oven. Call us.

! Why to stop there

The oven control carries line voltage and is reached only after removing covers.
Testing the board and harness separately avoids buying the wrong part.
We tell you the price up front, and the repair has 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.

1c311c31 questions

What does the oven control do?

It switches the heating elements, reads the temperature sensors and manages the door and fan. When it reports its own problem, the oven may stop cooking to stay safe.

Can 1c31 go away by itself?

Occasionally a power reset clears it. If the same code shows within a day or two, the control or its wiring still has a problem and should be tested.

Why do some combination ovens list the same code?

The same control design is used in combination models, so the code carries over. The check, testing the control and wiring, is the same on both.
