What F/4
actually means.
F/4 on the SINRT means the IGBT, which controls power to the induction coil, is malfunctioning. ZLINE is unusually firm here: turn the rangetop off at once, because running it on may damage other electronics.

What to do when F/4 shows on the cooktopKind of codeInduction power and coils
An induction zone could not drive its coil as the board planned: no pan was detected, the current ran too high or too low, or the power stage reported trouble. The pan base, the supply voltage and a clogged air intake are checked before the coil or the power board is replaced, and a top that trips its breaker is left switched off until then.
Usually leads toInduction board and coil repair
Induction zones that stop sensing pans, cut out, buzz or show codes, traced to the power boards, the coils, their sensors and the links to the controls.
Shows up asCooktop Burner or Element Won't Turn Off
A gas flame keeps burning, a coil or radiant ring stays red, or an induction zone keeps heating after its knob or key has been set to off.
