Source: https://jaxapplianceservice.com/brands/la-cornue/ Hand-built French ranges that almost nobody in this market will touch. We service Château, Grand Palais and CornuFé burners, ovens, controls and door hardware. Product lines: Château, Grand Palais 180, CornuFé, Flamberge Rotisserie, Coup de Feu. Model prefixes on the data plate: Château 75, Château 90, Château 120, Château 150, Grand Palais 180, CornuFé 90, CornuFé 110. ## Faults we see on these - Burner lights then drops out - failed thermocouple or flame-failure safety valve - Spark ignition module clicking continuously after a boil-over or under a wet burner cap - Vaulted oven drifting off setpoint from a tired thermostat or a failing element - Coup de Feu solid top slow to reach working temperature - Heavy brass-trimmed doors sagging on their hinges and no longer sealing - Flamberge rotisserie motor failure - Incorrect propane orifice or regulator setup after a conversion, giving lazy yellow flames - Long parts lead times from France on anything cosmetic or cabinet-specific ## What we service La Cornue builds hand-assembled ranges in France in very small numbers, which is exactly why most repair companies in North Florida will not take the call. We do. - **Château** — the flagship, in 75, 90, 120 and 150 widths, with the vaulted oven, configurable top plate and optional Coup de Feu solid French top. - **Grand Palais 180** — the 180cm range, usually with twin ovens and a wide top plate. - **CornuFé** — the smaller, more conventional range, sold in 90 and 110 widths and far more common in this market than the Château. - **Flamberge** — the rotisserie option, when it is fitted. - **Matching ventilation** — the hoods specified with these ranges, including remote-blower installations. La Cornue plates identify the range by collection and width rather than a coded model prefix, and the serial plaque is what parts get ordered against. Photograph it before you call anyone. ## What actually fails Nothing exotic. The failures on a La Cornue are the failures of any high-quality gas and electric range, and they respond to the same disciplined diagnosis. The most common call is a burner that lights and then dies the moment the knob is released. That is the flame-failure safety system: the thermocouple is no longer proving flame to the safety valve, so gas is cut. It is a repair, not a replacement. Second most common is continuous spark clicking. After a boil-over, moisture in a burner cap or a switch will do it, and drying it out fixes it. If it keeps clicking dry, the ignition module is done. On the oven side, the complaint is nearly always that the vaulted oven no longer holds a temperature — cooler than the dial, or swinging wide. That is a thermostat or an element, and it is worth measuring rather than guessing, because the vaulted oven's radiant behavior means the setpoint and the temperature at the food are not always the same number. The Coup de Feu is a solid plate over a dedicated burner. If it takes forever to come up, the burner and its gas supply are the place to look, not the plate. Then there is hardware. These doors are heavy, and the brass trim adds to it. Hinges and springs go out of adjustment over years of use, the door stops sealing, and the oven suddenly performs badly for a reason nobody associates with a door. One more, specific to this market: a lot of these ranges are on propane rather than natural gas. If the orifices and regulator were not set correctly at conversion, you get lazy yellow flames, sooting on the pan bottoms and burners that will not simmer cleanly. That is a setup problem, and it is fixable. ## Parts and why they matter La Cornue is now part of Composition Brands, the independent platform that took over Middleby's residential kitchen business through affiliates of 26North. Anyone still calling it a Middleby brand is working from stale information — which also tells you something about how current their parts channel is. Functional parts move at a reasonable pace. Cosmetic and cabinet parts — enamel panels, brass trim, specific door components — come from France and take as long as they take. We quote the real lead time before you approve anything, because on a range like this the wait is part of the decision. ## Independent service and your warranty We are an independent appliance repair company. We are not affiliated with, authorized by, or endorsed by La Cornue. If your range is inside its factory warranty, use the manufacturer's own service channel for covered work. Once it is out of warranty, using an independent shop does not void anything. Under the Magnuson-Moss Warranty Act a manufacturer cannot void your warranty solely because an independent company did the work or a non-original part was used. That protects you; it does not mean La Cornue pays us. Diagnostic is flat, credited toward the repair when you approve it, with a written estimate first. Monday to Friday 8am to 6pm, Saturday 9am to 4pm, out to about a 40 mile drive from Fruit Cove. ## Questions people ask **Will you actually work on a La Cornue?** Yes. Most shops in this market decline them because the ranges are hand-built, the documentation is thin and the parts come from France. We treat them as what they are - a gas and electric cooking appliance built to a very high standard, with conventional failure modes. **Are you authorized by La Cornue?** No. We are an independent appliance repair company and we are not affiliated with, authorized by, or endorsed by La Cornue. We service the ranges and source genuine OEM parts through the manufacturer's US channel. **My burner lights and then goes out as soon as I release the knob. Why?** That is the flame-failure safety system doing its job. The thermocouple or its safety valve is no longer proving the flame, so gas is being shut off. It is a common, repairable fault and not a reason to replace the range. **How long do La Cornue parts take to arrive?** Functional parts such as thermocouples, valves, igniters, elements and thermostats are usually reasonable. Enamel panels, brass trim and cabinet-specific parts can take considerably longer because they come from France. We quote the lead time before you approve. **Is a La Cornue worth repairing?** Almost always. These ranges are replacement-cost appliances measured in five figures plus cabinetry and gas work, and the parts that fail are mechanical and electrical components with real service lives. Repair economics on a La Cornue are rarely close. **Do you work on the matching La Cornue hood?** Yes. Blower motors, speed controls, switches and lighting on the matching hoods are all serviceable, and we handle remote-blower installations where the motor sits in the attic or on the roof. --- Hours: Mon–Fri 8am–6pm · Sat 9am–4pm.
