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. ### 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](/services/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](tel:+13056143699) and describe what the display is doing before booking anything.
