La Cornue oven: an electric oven that does nothing, and the maker’s three questions before anything else
La Cornue — an indicator rather than a code. For an oven that will not come on at all, the guide asks three things in order: is the power on, is the range supply on at the circuit breaker, and — if you are using the multifunction oven — have you actually set a cooking function.

What we can confirm
Signal Oven not coming on, 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 coming on
For an oven that will not come on at all, the guide asks three things in order: is the power on, is the range supply on at the circuit breaker, and — if you are using the multifunction oven — have you actually set a cooking function. The third one is not condescending. A multifunction oven with a temperature set and no function selected sits there doing nothing, which is exactly what a dead oven looks like, and on a range with two different ovens it is an easy thing to get wrong.

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
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

About La Cornue oven: an electric oven that does nothing, and the maker’s three questions before anything else
What the appliance is actually doing
For an oven that will not come on at all, the guide asks three things in order: is the power on, is the range supply on at the circuit breaker, and — if you are using the multifunction oven — have you actually set a cooking function. The third one is not condescending. A multifunction oven with a temperature set and no function selected sits there doing nothing, which is exactly what a dead oven looks like, and on a range with two different ovens it is an easy thing to get wrong.
Quoted rather than interpreted
Is the power on? If not there may be something wrong with the power supply. ... Is the range supply on at the circuit breaker?
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 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
- Check that a cooking function is selected, not just a temperature. This is the maker's own third question and it costs nothing.
- Check the breaker for the range.
- Check any isolating switch, which on a fitted kitchen can be behind a cabinet door.
- Confirm which oven. On a dual-fuel range the gas side has its own separate failure list.
- If the supply is proved and a function is set, have it measured — element, sensor and control, in that order.
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.
