La Cornue oven: the oven lamp, which the maker states plainly is not a warranty part
La Cornue — an indicator rather than a code. The guide expects the owner to do this one, and says so: the bulb has probably blown, you can buy a replacement — which is not covered under the guarantee — from most electrical stores, and what you ask for is a 40 W 120 V halogen lamp, G9 fitting.
- 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 Oven light not working, 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 light not working
The guide expects the owner to do this one, and says so: the bulb has probably blown, you can buy a replacement — which is not covered under the guarantee — from most electrical stores, and what you ask for is a 40 W 120 V halogen lamp, G9 fitting. Turn off the power, let the oven cool, open the door, take the shelves out, and unscrew the bulb cover counter-clockwise — the guide warns that it may be very stiff. It is one of the few genuinely customer-serviceable things on the appliance and we would rather tell you than take the call.

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
level, tray size, loading and the door seal come before any part
a vaulted oven is not the oven you had before

What the appliance is actually doing

Quoted rather than interpreted
Ask for a 40W - 120V halogen lamp (G9)
From the CornuFé 90 Albertine induction installation and user guide (U111110-02a, 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
- Turn the power off and let the oven cool completely.
- Ask for a 40 W 120 V halogen lamp with a G9 fitting — that is the figure in La Cornue's US Albertine guide. Their CornuFé 110 guide prints 230 V for the same lamp, which is a European figure; on a US range the lamp is a 120 V one. If in doubt, take the old lamp to the shop.
- Expect the cover to be stiff. It unscrews counter-clockwise and it often needs real grip.
- Handle the new lamp with a cloth rather than bare fingers.
- Stop if a new lamp does not light, or if two or three have gone at once — that is a socket or a supply problem and it is worth a visit.
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.
