Hard to say. It might be anything from a broken switch at perhaps a few hundred dollars to an induction component at one third the original cost of the unit to fix.

Mine just did too, so am going to call for repair. Parts are under warranty but not, of course, labor. Can you believe the gall? My Wolf ovens are fabulous and fully covered. Viking won't be in my next home. I'll let you know what it costs - I'm in CT.
