La Cornue appliances are a fixture of the luxury kitchens across Bronxville and the surrounding towns, and this guide covers what tends to go wrong, how we diagnose it, and how to keep a La Cornue running well. Our focus is hand-built French ranges.
La Cornue ranges are hand-built and mechanical; they do not use a numeric fault-code system, so we diagnose by symptom to cause. Below are the models we service, the problems we see most, and answers to the questions owners ask.
Models We Service
- Chateau series ranges (Chateau 90, 120, 150)
- CornuFe 90 and CornuFe Albertine ranges
- Grand Palais flagship ranges
- Vaulted-oven gas and dual-fuel configurations
Symptom and Error Guide
| 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 |
What We Check
- 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
Model-specific La Cornue parts and a correct diagnosis are what keep a repair lasting. When a La Cornue shows an early sign of trouble, addressing it promptly usually means a smaller, diagnostic repair.

When to Call a Technician
