KitchenAid Wall Oven Code 1c1c: Keypad or its wiring

What 1c1c means

On KitchenAid wall ovens and combination wall ovens, the lower-case code 1c1c indicates a possible problem with the user interface keypad or the wiring to it. The family of four-character lower-case codes is not tied to a single model here, so we match it to your oven during the visit. Expect unresponsive keys or a display that stops. It may also appear after a spill reaches the panel.

Common causes of 1c1c

User interface keypad that is not registering
Wiring between the keypad and the oven control that is loose or damaged

✓ One safe check you can try

1. Press Cancel and wipe the panel with a barely damp soft cloth. 2. Switch the oven off at its breaker for one minute. 3. Restore power and test one simple function. 4. If 1c1c returns, stop using the oven and call us.

! Why to stop there

The keypad ribbon runs inside the control housing of a built-in oven.
Opening it exposes live parts.
We quote first and fix only what testing shows.

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.

Can spills cause 1c1c?

Moisture on the panel can confuse a keypad. Wipe it dry and reset power. If the code stays, the keypad or wiring needs a technician.

Does the oven still bake?

Often not while the code is active. Treat the oven as out of service until it is checked. Often not while the code is active, so treat the oven as out of service until it is checked by a technician.
