Error and Fault Codes
La Cornue does not publish a broad numeric fault-code chart, so we diagnose from a symptom, cause, and fix method backed by hands-on testing. This table shows the symptoms we see most and how we approach each one.
| Symptom | Likely Cause | What We Check |
|---|---|---|
| Burner will not light | A wet or dirty igniter, or a gas-supply issue | Clean and dry the burner, verify the gas path |
| Oven not heating | An igniter, element, or thermostat fault | Test the igniter or element and the thermostat |
| Uneven baking | Vaulted-oven airflow or thermostat drift | Check burner performance and recalibrate |
| Weak flame | A port blockage or regulator issue | Clean the ports and check the regulator |
Common Problems We Fix
- A range burner not igniting on a Chateau or CornuFe
- A vaulted oven slow to heat or baking unevenly
- A weak or uneven burner flame
