Burner heads and caps that go back slightly wrong, or go back wet, are the leading cause of this call. After that the guide asks whether other gas appliances in the house are working, whether the burners spark when the knob is pushed in, and whether the power is on — because a spark-ignition range with no electricity has no spark. ### Quoted rather than interpreted > If only one or all the cooktop burners will not light, make sure that the parts have been replaced correctly after wiping or removing for cleaning. From the CornuFé 110 dual fuel installation and user guide (U107101-21e), in a User Guide & Service Manual downloaded from La Cornue’s own site. Nothing on this page is decoded beyond what that sentence says. ### Which machines this one applies to La Cornue gas and dual fuel ranges. La Cornue publishes three codes in the whole of its US documentation and its Château guide carries no troubleshooting section, so a behavior missing from this archive is not proof that your appliance cannot do it — the maker simply never wrote a table for it. What its guides do document, they document in sentences, and those are on this site under the maker’s own wording. The model number, and which top the range was ordered with, settle what any of it means. ### What to do about it - Take the cap and burner head off and refit them correctly and dry. This is the maker’s own first check. - Check whether other gas appliances in the house are working, which is how the guide suggests testing the supply. - Watch for a spark when you push the knob in. No spark points at the power or the ignition rather than the gas. - Check the electrical supply and breaker, because ignition needs it. - Count how many burners are affected. One is local to that burner; all of them is supply, power or the module. ### Where this goes next The job this usually becomes is [surface burner and igniter service](/services/surface-burner-and-igniter-service/), and every one of those pages carries a starting figure and the reasons that move it.
