La Cornue induction hob: a crack in the hob surface — disconnect it immediately, in the maker’s own words
La Cornue — an indicator rather than a code. This is the only entry in La Cornue's troubleshooting section written as an instruction rather than an explanation, and the instruction is unambiguous: disconnect the cooker immediately from the power supply, arrange for its repair, and do not use it until after the repair.
- From $95 diagnostic, credited to the repair

- OEM parts available on order
- In writing the price, before anything is opened
What we can confirm
Signal Crack in the hob surface, 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
Crack in the hob surface
This is the only entry in La Cornue's troubleshooting section written as an instruction rather than an explanation, and the instruction is unambiguous: disconnect the cooker immediately from the power supply, arrange for its repair, and do not use it until after the repair. The reason is what the glass is for — it separates the coils and the electronics beneath it from anything spilled on the surface. A cracked hob that still heats is not evidence that it is safe to use.

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
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
usually a burner head refitted wrongly or wet after cleaning

About La Cornue induction hob: a crack in the hob surface — disconnect it immediately, in the maker’s own words
What the appliance is actually doing
This is the only entry in La Cornue's troubleshooting section written as an instruction rather than an explanation, and the instruction is unambiguous: disconnect the cooker immediately from the power supply, arrange for its repair, and do not use it until after the repair. The reason is what the glass is for — it separates the coils and the electronics beneath it from anything spilled on the surface. A cracked hob that still heats is not evidence that it is safe to use.
Quoted rather than interpreted
Disconnect the cooker immediately from the power supply and arrange for its repair. Do not use the cooker until after the repair.
From the CornuFé 110 induction installation and user guide (U111136-03, January 2023), 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 induction cooktops and rangetops, and the electric and multifunction ovens. 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
- Isolate the cooktop at the supply now, at the breaker if there is no accessible switch.
- Do not put a pan on it, and do not test the zones to see which ones still work.
- Keep it dry. No wet cloths and no cleaning products anywhere near the crack.
- Photograph it once, cold and dry — one clear picture tells us whether it is a full panel or an insert and how it needs to be ordered.
- Expect the coils and electronics to be inspected as part of the repair, not just the glass replaced.
Where this goes next
The job this usually becomes is induction glass replacement, 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.
