La Cornue cooktop repair: what to know
La Cornue cooktops and the cooking surfaces on its ranges come in many configurations, including gas burners, simmer plates and French tops on some Château models. Gas burners rely on electronic ignition and, on many models, flame-failure devices that close the valve if the flame goes out. A French top is a solid plate heated from below, which behaves very differently from open burners.
Worth knowing about La Cornue: La Cornue ranges are built by hand in France, often to order, and each one has to be approached as its own installation. Also, La Cornue sticks to heavy construction, mechanical controls and serviceable burners, which keeps these ranges repairable for decades.
Common La Cornue cooktop failures
These are the failure points to check first on a La Cornue cooktop:
- Burner ignition failing or clicking
- Flame-failure devices closing the gas valve
- Burner ports clogging
- French top heating unevenly
- Knob valves sticking
A list like this points the diagnosis in the right direction, but one symptom can come from parts at very different prices, so the cause is confirmed at your home before you get a quote.
How we diagnose a La Cornue cooktop
Whatever the brand, on a cooktop we check igniters and burner ports on gas; elements, switches and the control board on electric and induction — a gas burner that won't light or flames unevenly almost always has a clogged port or a bad igniter, not a bad valve.
One cooktop symptom that's easy to misread is an induction cooktop throwing an error during long, hot cooking, which is often the unit protecting itself from overheating or poor ventilation rather than a failed board.
Built-in La Cornue equipment: what the visit involves
Most La Cornue equipment is built into cabinetry or anchored in place, so the visit starts with working out how to reach it. We allow a longer appointment and protect floors, cabinet faces and countertops before anything moves.
It changes the economics as well. Replacing a fitted La Cornue cooktop usually means cabinet or countertop work on top of the new appliance, so a failure that would retire a freestanding unit is usually still a repair here.
Before the visit
The model and serial number are on the underside of the cooktop or the burner box, often visible from the cabinet below. A photo of that label is the most useful thing you can send when you book: it tells us which La Cornue platform you have and which parts to bring.
On gas, make sure each burner cap is seated and the ports are clean and dry. On electric, note whether one element or all of them are out. On induction and touch controls, write down any error code.
In San Antonio, keep in mind the many homes cooking on CPS Energy natural gas, and pro-style cooktops in remodeled kitchens whose high-output burners need their own kind of service.

A French top is a solid plate heated from a burner beneath, hottest in the center. If it heats unevenly or not at all, the burner, igniter or valve underneath is checked. The plate itself rarely fails.
Many models have a flame-failure device that closes the valve if it doesn't sense a flame. Hold the knob in for several seconds after lighting. If it still goes out, the thermocouple may be dirty or failed.
Gas models can often be converted with the correct parts, but the procedure depends on the configuration. It should be done by someone qualified to work on gas.
A dead zone on an induction top can be the pan, a cooling fan or a power board, and a gas burner that won't light can be a cap or a spark module. Each needs its own test before a part is chosen.
