Model overview
The name on the label is the most useful detail for a repair request on this La Cornue range, so start there. Without a confirmed size, a technician relies on the full Château name to check the correct oven and cooktop configuration. Describe a burner that keeps clicking, a control panel that goes unresponsive, or an oven that will not hold its set point. Add what the convection fan or oven light is doing, along with any uneven baking. Those specifics narrow the parts list quickly. Homeowners in Los Angeles and Orange County should write the exact name from the label, the symptom, and any code shown in the booking form.
Château is a La Cornue range. The model number is printed on the rating label, usually on the frame behind the storage or warming drawer, or around the oven door opening; match it letter for letter before booking, because a single letter can change parts.
