La Cornue cooktop: burners that will not light, and the maker’s first suspicion is the cleaning
La Cornue — an indicator rather than a code. La Cornue's own checklist for burners that will not light starts somewhere unexpected and entirely justified: make sure the parts have been replaced correctly after wiping or removing them for cleaning.
- From $95 diagnostic, credited to the repair
- 59 cities and neighborhoods covered

What we can confirm
Signal Cooktop burners will not light, from the manufacturer's own documentation
This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.
The signal
Cooktop burners will not light
La Cornue's own checklist for burners that will not light starts somewhere unexpected and entirely justified: make sure the parts have been replaced correctly after wiping or removing them for cleaning. 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.

What else belongs to the cooktops and rangetops
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
the hob electronics are too hot and have shut down
the electrical connection is wrong and the hob has latched off
an internal problem that needs a technician
no display, which the maker puts down to the supply
the protective device keeps operating and that is a test, not a reset
it will not switch on, and both of the maker's checks are upstream
the zone is still hot — an indicator, not a problem
the zone cannot see a suitable pan, and pan size is the usual reason
disconnect it immediately and do not use it until it is repaired
pan noise on induction is normal at high power
scratches do not come out, and pan bases are usually the cause
the flame safety device is not holding in

About La Cornue cooktop: burners that will not light, and the maker’s first suspicion is the cleaning
What the appliance is actually doing
La Cornue's own checklist for burners that will not light starts somewhere unexpected and entirely justified: make sure the parts have been replaced correctly after wiping or removing them for cleaning. 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, and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 614-3699 and describe what the display is doing before booking anything.
