Model overview
A technician arriving for the Château Grand Palais 180 cooktop from La Cornue will start by asking which zone is affected and what the display shows. Having the code and the zone number ready makes that first conversation easier. Igniters that keep clicking and zones that will not heat are the usual pair of reports, and touch controls that lock out can add a third. Write those details down before the visit, along with the 70 7/8 inch size from the label. Owners in Los Angeles and Orange County should put the full model name, the affected zone, and any error code in the booking form.
Château Grand Palais 180 cooktop is a La Cornue 70 7/8" rangetop. The model number is printed on the rating label, usually on the underside of the unit; many owners also have it on the warranty card or installation papers; match it letter for letter before booking, because a single letter can change parts.
