Model overview
Daily cooking on a 53-inch surface puts a lot of heat across the cooktop, and the Château 135 WD cooktop from La Cornue tends to show that wear through its controls first. Touch panels that flicker or lock out after a long session are common complaints, as are igniters that keep clicking before a burner lights. Report any error code on one zone exactly as it displays, since codes often point to a single area. A zone that never reaches heat also belongs on the list. Owners in Los Angeles and Orange County should include the Château 135 WD cooktop model number, the affected zone, and what the controls were doing when the trouble appeared.
Château 135 WD cooktop is a La Cornue 53 1/8" 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.
