It is published openly on its own site under **Resources**, in two sections: *Château Specs & Manuals* and *CornuFé Specs & Manuals*. The problem is that there is no single manual. There are dozens, split by model and by fuel, and picking the wrong one gives you confident answers to somebody else's appliance. ## What is in which **The Château G4 installation and user guide** covers the gas and dual-fuel ranges — the ones most of this catalog consists of. Installation, gas and electrical requirements, operation, cleaning, cooking notes. It contains **no troubleshooting section at all**. That is not an omission. A gas Château has no control system, no display and nothing stored; there is nothing to list. If you are hunting through it for a error-code table, you can stop. **A separate G4 guide** covers the all-electric and induction versions of the same ranges. Different document, different content, and the one you want if your Château has an induction top — remember that when an all-induction cooktop is specified the ovens are always electric too. **The CornuFé guides come in four**, and this is where people go wrong: 90 dual fuel, 90 induction, 110 dual fuel, 110 induction. Each has its own troubleshooting section, written in sentences rather than as codes — and the induction ones are the only place in the whole of La Cornue's US documentation where a error code is printed. **The Château Tourelle wall oven** has its own installation and user guide, dated November 2025. Its own cutout dimensions, its own electrical requirements, its own everything. It is not the range's oven. **The hoods** have separate guides again, and there are several: the Château motorized hood, the motorized island hood, the Suprême motorized hood, the CornuFé 90 and 110 hood, and the newer CornuFé Hood Collection. **Older ranges** are still covered. The Centenaire installation and user guide for the 2008 to 2016 models is still published, which is a company telling you what service life it expects. ## The trap: a figure the maker disagrees with itself about The oven lamp. The **US Albertine guide** says to ask for a *40W – 120V halogen lamp (G9)*. The **CornuFé 110 guide** says *40 W – 230 V* for the same lamp in the same position. 120 V is the US figure. 230 V is European, and the CornuFé guides are visibly adapted from a European original — the same documents refer to a Residual-Current Device rather than a GFCI. That is one small example of a general rule: these documents are per model and per fuel for a reason, and reading across them produces answers that are confidently wrong. Breaker sizes, oven capacities and burner ratings all differ between the 90 and the 110, and between dual fuel and induction. ## What the troubleshooting sections actually contain Worth knowing before you go looking, because the format surprises people. Where La Cornue does document problems, it does it in prose rather than as a code table: - what to do about a burner that goes out when you release the knob — hold it in slightly longer, and the safety device explanation behind that;- burners that will not light, starting with whether the parts were replaced correctly after cleaning;- an excessively hot fascia, which it attributes to a failed cooling fan;- steam at the rear grille, which it says is normal on food with a high water content;- a noisy oven fan, which it says is normal as the oven heats;- an oven not coming on, where its third question is whether you have set a cooking function;- an oven getting hotter as the range ages, where it names the thermostat;- uneven cooking, with the dish-of-water level test and the door-seal check;- and the oven lamp, which it says plainly is not a warranty part. Every one of those is published on this site as its own page, with the document it came from named and the maker's own wording quoted. That is deliberate: a documented condition is worth more than an invented code. ## The three codes, and where they live **E2** — the electronic unit is too hot; check the installation and the ventilation. **U400** — the cooker has been incorrectly connected; the control switches off after about a second and the code stays displayed permanently. **Er** with a number — an internal problem the user cannot put right. All three come from the CornuFé induction guide. All three belong to induction and all-electric models. None of them can appear on a gas range. ## And the symbols PDF everybody is looking for The mode symbols are in the guide for whichever multifunction oven you have — the CornuFé oven or the Tourelle — rather than in a separate document. If you cannot find yours, the short version is on this site: a fan in a circle is convection, a bare fan is defrost with no heat, two bars is conventional baking, a top bar is broil, a bottom bar is base heat. And if your Château has no symbols at all, nothing is missing. A vaulted gas oven has a thermostat and a broil control, and that is the entire interface. --- **[Read full article: Finding the Right La Cornue Manual, and What Is Actually in It](https://la-cornuemiami.support/blog/finding-your-la-cornue-manual/)**
