KitchenAid Induction Cooktop Code F58: concern about the power control board

What F58 means

KitchenAid induction cooktops, for example the KCIG550JSS, show F58 when there may be a problem with the Cooktop Power Control Board or the wiring around it. The board is what energizes the induction coils. Owners find zones that will not warm, or a cooktop that cuts out, with F58 on the display. The board runs the power side, so no heat is the usual result, and wiping or cookware changes will not help at all.

Common causes of F58

The power control board failing
Wiring to the board damaged by heat or vibration
A plug or terminal that has loosened
Power quality trouble reaching the board

✓ One safe check you can try

1. Switch all zones off. 2. Turn the cooktop breaker off for a minute and back on. 3. Check the display and try a single zone with an induction pan. 4. Book a visit if F58 appears a second time, and leave the cooktop idle until then.

! Why to stop there

The board sits beside high-voltage parts.
Diagnosing it needs insulated tools and training.
We write the price down before work and give a 30-day warranty.

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.

F58F58 questions

How do F42, F43 and F58 compare?

They all name the power control board and its wiring. Each number marks a different internal check, so we use them as a starting clue and then confirm with testing.

What can I do while I wait for service?

Leave the cooktop off at the breaker if you will not be using it. Cook on another appliance until it is checked, rather than resetting again and again.

Will F58 damage my pans?

No. The code concerns the cooktop's electronics, not the cookware. Your pans are fine, though they will not heat until the cooktop is repaired. It also does not harm food, because a zone that is not heating never gets hot.
