--- title: "La Cornue oven: the note of the oven fan changing as the oven heats up is normal" description: "La Cornue oven: the note of the oven fan changing as the oven heats up is normal: la Cornue — an indicator rather than a code." url: "https://la-cornuemiami.support/error-codes/oven-fan-is-noisy/" date_modified: "2026-09-04" Appliance type: "Ovens, Ranges" --- # La Cornue oven: the note of the oven fan changing as the oven heats up is normal ### What the appliance is actually doing The guide’s line on this is one sentence: the sound of the oven fan may change as the oven heats up, and this is perfectly normal. It is genuinely useful to know, because a fan whose pitch rises during preheat sounds exactly like something going wrong. What is not in that category, and is worth reporting, is a rumble that gets worse over weeks, a regular tick or scrape at any temperature, or a fan that has become audible from another room. ### Quoted rather than interpreted > The sound of the oven fan may change as the oven heats up – this is perfectly normal. 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 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 - Listen to whether the note changes or the volume grows. A changing note is normal; growing volume is not. - Note whether it is present cold as well as hot. A noise only at temperature is often a bearing. - Listen for a tick or a scrape, which is contact rather than wear. - Compare the two ovens on a dual-fuel range if both have fans — one noisy and one quiet is the answer. - Report a noise that has changed rather than one that has always been there. ### Where this goes next The job this usually becomes is [convection fan repair](/services/convection-fan-repair/), 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.
