La Cornue range: the fuse blows or the residual-current device trips regularly, and the maker sends this straight to an engineer
La Cornue — an indicator rather than a code. This is one of the shortest entries in La Cornue's own troubleshooting section and one of the clearest: where the house fuse blows or the residual-current device trips repeatedly, contact your installer or a qualified repair engineer.
- From $95 diagnostic, credited to the repair
- 59 cities and neighborhoods covered
- OEM parts available on order
- In writing the price, before anything is opened
What we can confirm
Signal Fuse or RCD keeps tripping, 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
Fuse or RCD keeps tripping
This is one of the shortest entries in La Cornue's own troubleshooting section and one of the clearest: where the house fuse blows or the residual-current device trips repeatedly, contact your installer or a qualified repair engineer. There is no owner check offered, and that is the right advice — a protective device operating repeatedly is doing its job, and the interesting question is what is making it operate. On a range that draws what these draw, resetting it and hoping is not a plan.

What it narrows down to
the protective device keeps operating and that is a test, not a reset

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
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
usually a burner head refitted wrongly or wet after cleaning

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
- Stop resetting it. A device that trips repeatedly is reporting something real.
- Note what was running when it tripped — which zones, which oven, and whether the hood or anything else was on the same circuit.
- Note whether it trips on switch-on or under load. They point at different things.
- Have the appliance and the circuit tested. Insulation resistance on the elements and coils, and the circuit's own rating against the appliance's requirement.
- Leave the range isolated until it has been tested if the tripping is frequent.
Where this goes next
The job this usually becomes is cooktop control and wiring repair, 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.
