Wolf Early Induction Code FC: Boost LED Error, Control Board

What FC means

FC appears on early Wolf induction cooktops, including the CT30I/S and CT36I/S. It reports a Boost LED error, meaning the control cannot drive or read the boost indicator light correctly, and the listed remedy is a new control board. You will see FC on the display, and boost may be unavailable or the burner controls may act oddly until the board is replaced.

Common causes of FC

Control board error in the Boost LED circuit
Touch control wiring to the board interrupted
Board damaged by a power surge or moisture

✓ One safe check you can try

1. Turn all burners off and wait for the glass to cool. 2. Wipe the control area dry; spilled liquid on the touch panel can confuse the board. 3. Switch the breaker off for one minute and restore it. 4. If FC stays, avoid the boost function and book a visit. Please leave the cooktop closed.

! Why to stop there

The board lives under the glass with live circuits, so we do not recommend owner testing.
Reading FC correctly matters: it points at the control board, and a wrong guess wastes money on parts.
You get a written price before any part is 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

Is FC the same as a burner problem?

No. FC concerns the Boost LED circuit on the control side. It is a board matter, so changing pans or cleaning the glass will not remove it.

Can I keep cooking with FC showing?

Sometimes the other burners still respond, but the code means the control is not healthy. We suggest stopping use until it is checked, mainly to avoid it spreading to other functions.

What does the repair involve?

We confirm FC on your cooktop model, quote the control board and labor in writing, and replace the board after your approval. A 30-day workmanship warranty covers our work.
