What makes it worth a page is how gradual it is. An oven that has drifted 30 degrees over three years has a cook who has adapted to it entirely, and the drift is only visible against a thermometer. ### Quoted rather than interpreted > If turning the temperature down using the oven control knob has not worked, or has only worked for a short time, then you may need a new thermostat. 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 - Put a thermometer on the middle shelf and run a full cycle, reading it every ten minutes. - Separate overshoot from settled temperature. Spiking on the way up and settling correctly is normal; settling high is not. - Note whether turning the dial down helps, and for how long. That distinction is the maker’s own test. - Check each oven separately on a dual-fuel range — they drift independently. - Expect your cooking to change when it is corrected. Three years of learned adjustments become errors in the other direction. ### Where this goes next The job this usually becomes is [oven thermostat calibration](/services/oven-thermostat-calibration/), 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.
