KitchenAid Smoothtop Cooktop Code F12: trouble with a cooking area or its wiring

What F12 means

On KitchenAid electric radiant touch-control cooktops such as the KCES550HSS or KECC664BSS, F12 points to a problem with a hotplate (a cooking surface, burner or element) or the wiring that feeds it. The affected cooking area stops heating, or the whole cooktop shuts down with the code on the display. Because the code names the cooking area side of the cooktop, a reset helps only if the problem was a momentary glitch. Owners often notice that one area stays cold while the display keeps the code.

Common causes of F12

A radiant element that has failed or cannot be driven
Wiring to the element that is damaged or loose
A connection that overheated and lost contact
A control that cannot power the cooking area

✓ One safe check you can try

1. Turn all cooking areas off and let the glass cool. 2. Look for visible cracks or damage on the surface, but do not lift the glass. 3. Switch the breaker off for a minute and back on, then test an area. 4. Should F12 come back, stop cooking on it and ring us.

! Why to stop there

An element or its wiring is under the glass and live.
Replacing them needs the right parts and safe handling.

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.

F12F12 questions

Which burner is affected by F12?

The code points to a cooking area or its wiring in general. Try each area in turn, and tell us which ones heat and which do not, so we can narrow it down.

Can I keep using the other areas?

It is better not to. A problem in the wiring or control can affect the whole cooktop, so leave it off until it has been looked at.

Will a reset fix F12?

A reset is worth one try, but it will not repair a failed element or damaged wire. If F12 returns, the hotplate or its wiring needs testing.
