La Cornue Château 165 Cooktop Repair in San Francisco

The Château 165 cooktop is a 65-inch Château G4 module. It brings the look of the Château cooking surface to kitchens that keep their ovens elsewhere, in a wall stack or a separate cavity, so the cooktop is set into the counter and the ovens are somebody else’s problem.

Installed over cabinets, not on a floor

That setup creates a different service situation from a free-standing range. Everything we need to reach lies under the counter: the supply connection, the valves, and the wiring for the ignition. In many Bay Area kitchens that space holds deep drawers, a pull-out or a pot rack, and clearing it is part of the visit. Tell us beforehand what sits below the top.

What goes wrong most often

• Flame that comes up lazy or lopsided on one burner.
• No spark, or a spark that arrives late.
• A burner that drops out when a pan is placed over it.
• Greasy build-up on caps and heads that blocks the ports.

Spilled sauce is the usual culprit for the last item, and cleaning a cap is an owner step. Let everything cool, wipe it gently, and dry it completely before placing it back. A cap that is wet or knocked sideways keeps flame from catching.

What we look at under the counter

A technician follows the gas path from the supply to each valve, then checks each igniter and its wiring, and finally the flame-safety parts that decide whether a burner stays on. A cooktop is also affected by the hood above it. If grease has built up in the hood or the duct, warm moist air can drift back down over the surface, so we notice the state of the ventilation too.
