KitchenAid Wall Oven Code 1c4c: Control reporting an internal issue

What 1c4c means

KitchenAid wall ovens and combination wall ovens display the lower-case code 1c4c when the oven control or its wiring may have a problem. The code is one of several in the 1c family that point at the same area. You are likely to see the oven stop mid-cycle or refuse to start, with 1c4c showing on the display. It can also show up between cycles.

Common causes of 1c4c

Oven control that is misbehaving
Wiring to the control with a bad connection

✓ One safe check you can try

1. Press Cancel and note whether the code stays. 2. Turn the breaker off for a minute, then back on. 3. Start a short bake to see if 1c4c reappears. 4. If it does, leave the oven off and call us.

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.
