Model overview
Large cooktops are usually matched to parts by model, so the Château 165 cooktop from La Cornue needs its exact number on every repair request. A 65-inch surface has more to check than a compact unit, which is why the technician will compare each symptom against that model's layout. When a zone will not heat, an igniter keeps clicking, or the touch controls lock out, the notes should stay in that order. An error code on one zone gives a clear starting point. Households across Los Angeles and Orange County can include the model, the code if any, and the first symptom in the booking form.
Château 165 cooktop is a La Cornue 65" 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.
