# 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](/services/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](tel:+13056143699) and describe what the display is doing before booking anything.
