KitchenAid Built-In Microwave Code 1c1c: keypad or wiring problem

What 1c1c means

On KitchenAid built-in microwaves and microwave-wall oven combinations, such as the KMBP100ESS or KOCE500ESS, code 1c1c points to the user interface and keypad, or the wiring that connects it to the control. In plain words, the oven is not reading the touch pad reliably. You may see the code appear when you press a pad, or find that some keys no longer respond while others still work.

Common causes of 1c1c

The keypad or touch panel is not sending clean signals to the control
The wiring between the keypad and the control is loose or damaged
A one-time electrical glitch has left the control confused

✓ One safe check you can try

1. Press Cancel and see whether the code clears. 2. Wipe the touch panel with a soft damp cloth; moisture and grease can mimic stuck keys. 3. Switch the unit off at its breaker for one full minute, then restore power. 4. Wait a minute and press a few pads to see if the code returns. If it comes back, stop using the oven and book a visit.

! Why to stop there

The keypad sits behind the front frame, and getting to it means opening live electrical parts
Replacing the wrong part is costly, and the wiring needs to be tested with instruments
We confirm the cause first and quote the price in writing before any work starts

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

Why does 1c1c show up when I press a pad?

The code reports that the keypad or its wiring is not behaving. A pad that registers twice, or not at all, gives the control a reading it cannot accept, so it posts the code instead of starting a cycle.

Can I still use the oven while 1c1c is showing?

Often not. Many units stop heating until the code is cleared, and running one with a misbehaving keypad is not wise. Try one breaker reset; if the code returns, wait for a technician.

Does 1c1c mean I need a new oven?

Rarely. The official meaning is limited to the keypad or its wiring, so a repair is usually far cheaper than replacement. We test first, quote the price before work, and back the repair with a 30-day workmanship warranty.
