Viking Designer Cooktop Code FC: Key Error With a Capital C

What FC means

On Viking Designer DETU series touch-control radiant cooktops, a capital FC on the timer display is a key error. The control stops all heating elements and shows the code. Do not confuse it with Fc, a small c, which means over temperature on this cooktop. Because the two differ only by letter case, read the display carefully, and tell us which one you see.

Common causes of FC

Touch key reading as pressed
Moisture on the touch panel
Touch key contact worn

✓ One safe check you can try

1. Turn all controls off. 2. Let the glass cool and dry the touch area. 3. Remove anything resting on the panel. 4. Reset power at the breaker after waiting one minute. 5. If FC returns, call us and say whether the C is capital or small.

! Why to stop there

Capital and small letters mean different things
The touch panel circuit lies under the glass
The control needs testing before parts are ordered

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.

FCFC questions

How do I tell FC from Fc?

Look at the second letter. A capital C is a key error. A small c is over temperature. They are different problems with different repairs.

Will cleaning help?

Sometimes, if moisture or grease makes a key read as pressed. Dry the panel and try again after a power reset. A photo of the display helps us confirm the letters before we arrive.

What if I am unsure of the case?

Describe the display to us or send a photo. We confirm before any work, quote in writing and give a 30-day workmanship warranty. Photos of the display help.
