La Cornue oven: steam at the rear grille and a puff when the door opens, both normal
La Cornue — an indicator rather than a code. When you cook food with a high water content the guide expects steam to be visible at the rear grille, and expects a momentary puff when the oven door is opened — with the sensible instruction to stand well back and let it disperse.

What we can confirm
Signal Steam from the oven, 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
Steam from the oven
When you cook food with a high water content the guide expects steam to be visible at the rear grille, and expects a momentary puff when the oven door is opened — with the sensible instruction to stand well back and let it disperse. It is on this page because a vaulted oven is a sealed cavity and people reasonably read visible steam as a seal problem. It is the opposite: a cavity holding moisture in until the door is opened is a cavity doing what it is meant to.

What else belongs to the ovens
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
an internal problem that needs a technician
the protective device keeps operating and that is a test, not a reset
the cooling fan may have failed
warm knobs above a working oven are normal
a fan whose note changes with temperature is normal
power, breaker, or no cooking function selected
the thermostat has drifted and the maker says replace it
level, tray size, loading and the door seal come before any part
a vaulted oven is not the oven you had before
a G9 halogen lamp, and the maker says it is not a warranty part

What the appliance is actually doing
When you cook food with a high water content the guide expects steam to be visible at the rear grille, and expects a momentary puff when the oven door is opened — with the sensible instruction to stand well back and let it disperse. It is on this page because a vaulted oven is a sealed cavity and people reasonably read visible steam as a seal problem. It is the opposite: a cavity holding moisture in until the door is opened is a cavity doing what it is meant to.
Quoted rather than interpreted
When cooking foods with a high water content (e.g. oven fries) there may be some steam visible at the rear grille.
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
- Notice what you are cooking. High-water-content food is the condition the guide names.
- Stand back when you open the door, and open it in stages during long roasts.
- Distinguish steam from smoke. Steam disperses; smoke means something is burning.
- Look at whether it is coming from the door edges rather than the rear grille — steam escaping at a corner is a seal matter.
- Do not treat normal steam as a reason to have the door adjusted.
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.
