Model overview
For the Château 150 cooktop from La Cornue, the model number matters more than the product name, because the same family can use different parts from one size to the next. Start the booking note with the complete model number from the label, then describe what the surface is doing. An error code on one zone, an igniter that keeps clicking, or a zone that will not heat each steer the diagnosis in a different direction. Touch controls that flicker or lock out add one more branch to check. Owners in Los Angeles and Orange County should note the 59-inch size next to the code exactly as it appears.
Château 150 cooktop is a La Cornue 59" 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.
