JennAir Wall Oven Code 1c1c: user interface or keypad problem

What 1c1c means

On JennAir built-in wall ovens such as the JJW2830DS and JJW2427DS, the code 1c1c says the user interface, meaning the keypad and display, or the wiring to it may have a problem. The control cannot trust what the touch keys are sending. You will see 1c1c on the screen, and buttons may respond slowly, press themselves, or stop working. The same code is also listed for combination ovens that include a microwave.

Common causes of 1c1c

User interface or keypad sending unreliable signals
Wiring between the keypad and the control loose or damaged

✓ One safe check you can try

1. Wipe the panel with a dry soft cloth and keep your hands dry. 2. Press Cancel and wait one minute. 3. Turn the oven breaker off for two minutes, then on again. 4. Try setting the clock. If 1c1c returns, stop using the oven and call us.

! Why to stop there

A keypad is a sealed assembly, and opening the front panel can damage its ribbon cable.
The matching part depends on the oven's model and trim.

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.

1c1c1c1c questions

Can moisture on the panel trigger 1c1c?

Moisture can confuse touch keys, so a dry wipe is worth a try. The official meaning still names the interface or wiring, so a code that keeps coming back needs a technician.

Will the oven bake if only some keys work?

We would not trust it. A keypad that sends wrong signals might start or stop a cycle without your input. Leave it off until the panel behaves normally.

Is 1c1c different from 1c2c?

The meaning listed for both is the same, a keypad or wiring problem. The different digits are how the control tells its own checks apart, and we test the interface for either one.
