On hob codes CB, CC and CR the Grand Castel 90’s top is entirely electric — two induction zones plus either an electric teppanyaki or a large induction plate, and no gas burner. La Cornue’s own literature notes this all-electric configuration is not UL-approved, which is worth confirming against the installed hob code before treating an unusual installation as a problem in itself.
Diagnosis on this hob starts at the control knob and the induction driver board; the single vaulted oven is unaffected by hob fuel and is checked the same way as on the gas codes.
