What FO
actually means.
On a Viking Designer electric cooktop, FO is a software error. The control stops the elements when its own program does not run as expected.

What to do when FO shows on the cooktopKind of codeBoards and communication
The touch board and the power board under the glass lost track of each other, or one failed its own start-up check. A power dip, a ribbon or harness pulled loose when the top was fitted, or moisture from a boil-over is ruled out before a board is replaced, and a cooktop that keeps heating while this code shows is switched off at the breaker.
Usually leads toTouch control repair
Glass touch keys and sliders that ignore a finger, start zones by themselves or stay locked, traced to the keys, the control board or the lock setting.
Shows up asCooktop Controls Unresponsive
Touch keys or a slider do nothing, the display lights but ignores every press, or a knob turns without starting its burner or element.

in this order.
Each step comes from Viking's own guidance for FO on its cooktops. Follow it to the end: the last card says whether this is a visit.
Switch the breaker off for a minute and back on.
Book a visit if FO shows again.
Write down whether FO appeared at switch-on or partway through cooking, and pass that on when you book.
What not to do
FO is not caused by the pan, the elements or spills on the glass. It comes from the control's own software.
