La Cornue oven: uneven cooking, and four checks the maker asks for before any part is considered
La Cornue — an indicator rather than a code. The guide's answer to uneven cooking is a list of things to correct that cost nothing, and it is the right list: do not use a baking tray larger than the specified size, turn a large item during cooking, leave space for heat to circulate when two shelves are loaded, place a tray centrally, check the door seal is undamaged and the catch is holding the door firmly against it — and check the range is level, using a dish of water on the shelf, which should be the same depth all over.

What we can confirm
Signal Oven not cooking evenly, 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
Oven not cooking evenly
The guide's answer to uneven cooking is a list of things to correct that cost nothing, and it is the right list: do not use a baking tray larger than the specified size, turn a large item during cooking, leave space for heat to circulate when two shelves are loaded, place a tray centrally, check the door seal is undamaged and the catch is holding the door firmly against it — and check the range is level, using a dish of water on the shelf, which should be the same depth all over. On a vaulted oven, which cooks by radiant heat rather than moving air, all six of those matter more than they would elsewhere.

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
steam at the rear grille is expected on wet food
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
a vaulted oven is not the oven you had before
a G9 halogen lamp, and the maker says it is not a warranty part

About La Cornue oven: uneven cooking, and four checks the maker asks for before any part is considered
What the appliance is actually doing
The guide's answer to uneven cooking is a list of things to correct that cost nothing, and it is the right list: do not use a baking tray larger than the specified size, turn a large item during cooking, leave space for heat to circulate when two shelves are loaded, place a tray centrally, check the door seal is undamaged and the catch is holding the door firmly against it — and check the range is level, using a dish of water on the shelf, which should be the same depth all over. On a vaulted oven, which cooks by radiant heat rather than moving air, all six of those matter more than they would elsewhere.
Quoted rather than interpreted
A dish of water when placed on the rack should be the same depth all over. ... If the range is not level, arrange for your supplier to level it for you.
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
- Do the water test. A dish of water on the middle shelf should sit at one depth all over; deeper at the back means the back needs raising or the front lowering.
- Check the tray size against the specification and place it centrally.
- Load one shelf and repeat. If a single centered tray bakes evenly, the problem was loading.
- Paper-test the door seal at eight or ten points around the perimeter.
- Turn large items during cooking, which is what the maker asks of a radiant oven rather than an admission of a problem.
Where this goes next
The job this usually becomes is oven door seal and hinge service, 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.
