Burner Will Not Ignite
Note which burner is affected, whether clicking continues, and whether flame appears.
A Handcrafted French Range
La Cornue ranges are built largely by hand, with signature vaulted ovens, heavy cast burners, and finishes in enamel and polished metals like brass. They are as much furniture as appliance, which shapes how you care for them: the finishes need gentle treatment, and the mechanical parts need the same clean, well-maintained attention any high-end range does.
La Cornue does not use consumer-facing numeric fault codes, so when a burner will not light or the oven is not heating right, diagnosis is symptom-based, reading the behavior and testing the ignition, gas, and oven components.
Care for Finish and Function
Clean enamel surfaces with gentle, non-abrasive products, and treat brass and polished metal according to the maker's guidance to protect the finish. Keep burner ports and igniters clean so lighting stays crisp, and wipe the vaulted oven so heat and airflow are not obstructed. Avoid harsh chemicals that can dull the finishes.
If a burner clicks without lighting, suspect a fouled port or the ignition components; if the oven will not reach temperature, the gas oven's igniter and safety valve or, on electric-equipped configurations, the element and control are the areas to check. Because these ranges are built to individual specifications, an experienced diagnosis matters.
Quick Reference
Oven Heats Unevenly
Record set temperature, measured result, preheat behavior, and any displayed code.
Control or Indicator Changes
Photograph the message and avoid repeated resets that erase the symptom history.
Gas Odor or Unsafe Flame
Leave the appliance off and follow utility or emergency guidance before requesting appliance service.
La Cornue Uses Symptom-Based Diagnosis
These handcrafted ranges do not present consumer numeric fault codes, so a technician reads the behavior and tests the ignition, gas, and oven components directly, with care for the finishes.

La Cornue Care FAQ
Does La Cornue Use Error Codes?
No. La Cornue ranges are diagnosed by symptom rather than consumer numeric codes, so a technician reads the behavior and tests the ignition, gas, and oven parts directly.
How Do I Clean the Enamel and Brass?
Use gentle, non-abrasive cleaners on the enamel and follow the maker's guidance for brass and polished metal. Harsh chemicals and abrasives can dull these handcrafted finishes.
Why Will My La Cornue Burner Not Light?
Usually a fouled burner port or an ignition fault. Cleaning the port often restores it; if not, the ignition components should be checked by a technician familiar with these ranges.
