Article overview
When a La Cornue range burner clicks but will not light: owner-safe checks, stop-use rules, and when to book range diagnosis.
A burner that clicks without lighting is one of the most common range complaints. This article stays on the cooktop. It is not a washer-lid or dryer-igniter article with the title swapped.
Owner-safe checks: confirm the knob is in the light position long enough, confirm the burner cap is seated, and confirm obvious debris is not bridging the igniter. If other burners light, the problem is likely local to that burner. If none light, you may have a wider ignition or gas-supply question — still not a DIY valve job.
Stop if you smell gas, if ignition is delayed with a puff of flame, or if you hear clicking for a long time with no flame. Ventilate and discontinue that burner.
Château is a La Cornue range family name used in the title of this existing article. We do not attach it to a foreign SKU. Diagnosis is still on-site: ignition path, then a written estimate if a repair is needed in Los Angeles County or Orange County.
