La Cornue builds its ranges by hand in France, and a Chateau or CornuFe is as much a piece of furniture as an appliance. These ranges use robust, largely mechanical gas and electric systems built for a lifetime of use, with vaulted convection ovens and heavy brass and steel construction. Servicing one means respecting both its engineering and its craftsmanship.
In the Noyac, Windward, and Sagaponack estate kitchens where a La Cornue is the showpiece, the calls we take most involve oven burners that will not stay lit, thermocouple and safety-valve issues, and surface burners needing attention. Because these ranges are mechanical at heart, most repairs are about the gas system, ignition, and calibration rather than electronics, and we treat the finish with care.
La Cornue does not use a numeric fault-code system; these are craftsman-built mechanical ranges. We diagnose them from symptom to cause and calibrate by hand.
Models We Service
We repair current and legacy La Cornue equipment, including:
- Chateau series ranges (Chateau 90, 120, 150)
- CornuFe 90 and CornuFe Albertine ranges
- Grand Palais flagship ranges
- Vaulted-oven gas and dual-fuel configurations
Symptoms, Causes & Fixes
La Cornue ranges are hand-built and mechanical; they do not use a numeric fault-code system, so we diagnose by symptom to cause.
| Code / Symptom | What It Means | What We Do |
|---|---|---|
Oven burner will not stay lit | Failed thermocouple or gas safety valve | Replace the thermocouple or valve, verify the flame holds |
Surface burner will not light | Clogged port, worn electrode, or valve issue | Clean the ports, replace the electrode, service the valve |
Oven heats unevenly | Burner calibration or thermostat drift | Recalibrate the burner and thermostat by hand |
Weak flame or low heat | Gas pressure or partially blocked burner | Verify gas pressure, clean and adjust the burner |
Electric element (dual-fuel) no heat | Failed element or connection | Replace the element, restore the connection |
Common Problems We Fix
- Oven burner that lights then goes out
- Surface burner that will not ignite
- Oven that heats unevenly or runs cool
- Weak or low flame on a burner
- Dual-fuel electric oven not heating
- Burner needing recalibration after a gas service
