The 75 cm Château cooktop uses the same hob hardware as the Castel 75 range, just without a vaulted oven beneath it — La Cornue’s own product page states it offers “all the possibilities of configuration” of the matching range width. That means a gas burner or induction zone on this cooktop is diagnosed exactly the same way as on a Castel 75 range of the same code.
Because it installs into a counter cutout rather than a range body, a leveling or fit complaint is checked against the cutout and support framing before assuming a hob part has failed.
Key Features
- A standalone stainless-steel cooktop for owners who already have wall ovens and want it at counter height
- 75 cm width, offered in the same gas-burner and induction hob configurations as the Castel 75 range
- No vaulted oven — this is the cooktop only
Most Common Issues on This Model
A gas burner not lighting, or an induction zone not detecting a pan (depending on which hob is fitted)
French top or power burner (gas hob) running cool at the rim
Cooktop not sitting flush or level in its counter cutout
