That is the whole of it, and it is here so that a normal characteristic of a range with brass knobs above a hot cavity is not mistaken for a problem. It is also worth distinguishing from the entry above: warm knobs are ordinary, an excessively hot fascia is not. ### Quoted rather than interpreted > Yes, this is caused by heat rising from the oven, and heating them up. From the CornuFé 110 induction installation and user guide (U111136-03, 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 - Close the oven door. Leaving it open is what the maker’s answer specifically warns against. - Compare with the fascia itself. Warm knobs with a normal fascia is ordinary. - Use a cloth if you are turning knobs during a long roast. - Notice whether it has changed. Knobs that have become noticeably hotter than they were point at the cooling fan entry rather than this one. - Do not fit aftermarket knobs to solve it — they are wear parts matched to the trim and the valve. ### 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.
