La Cornue range: knobs that get hot when the oven is on, which the maker confirms is normal

What we can confirm
Signal Hot knobs, 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
Hot knobs
Asked whether hot knobs can be avoided, La Cornue's answer is yes, this is caused by heat rising from the oven and heating them up — followed by one instruction: do not leave the oven door open. That is the whole of it, and it is here so that a normal characteristic of a range with brass knobs above a hot cavity is not mistaken for a problem. It is also worth distinguishing from the entry above: warm knobs are ordinary, an excessively hot fascia is not.

What else belongs to the ranges
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

What the appliance is actually doing
Asked whether hot knobs can be avoided, La Cornue's answer is yes, this is caused by heat rising from the oven and heating them up — followed by one instruction: do not leave the oven door open. That is the whole of it, and it is here so that a normal characteristic of a range with brass knobs above a hot cavity is not mistaken for a problem. It is also worth distinguishing from the entry above: warm knobs are ordinary, an excessively hot fascia is not.
Quoted rather than interpreted
Yes, this is caused by heat rising from the oven, and heating them up.
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 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
- Close the oven door. Leaving it open is what the maker's answer specifically warns against.
- Compare with the fascia itself. Warm knobs with a normal fascia is ordinary.
- Use a cloth if you are turning knobs during a long roast.
- Notice whether it has changed. Knobs that have become noticeably hotter than they were point at the cooling fan entry rather than this one.
- Do not fit aftermarket knobs to solve it — they are wear parts matched to the trim and the valve.
Where this goes next
The job this usually becomes is diagnostic visit, 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.
