--- title: "Ranges" description: "La Cornue ranges: the range is what La Cornue makes, and everything else in the line exists around it." url: "https://la-cornuemiami.support/appliances/range/" date_modified: "2026-09-03" Appliance type: "Ranges" --- # La Cornue ranges ### Nine sizes, and the configuration matters more than the size La Cornue’s current range line runs from the 23.6-inch Castel 60 to the 70.9-inch Château Grand Palais 180, with the Castel 75, Grand Castel 90, Châtelet 135, Château 120, 150 and 165 in between, and the factory-built CornuFé 90 “Albertine” and CornuFé 110 alongside them. What decides a repair, though, is the top configuration code that came with the order — N1 through N9 on a 180, K1 through K6 on a 150, C1 through C5 on a Grand Castel 90 — because that code is what says whether the range in front of us has two gas burners and a French top, a lava-rock grill, a pair of induction zones or a teppanyaki plate. Two ranges with the same model number can need entirely different parts. When you call, the size and the code together tell us more than a photograph does. ### Three kinds of range, and it changes the whole parts list **Dual fuel** is the Château 120 and everything above it: a vaulted gas oven with an electric broiler on one side, a vaulted electric oven on the other. Two different appliances in one cabinet, with two thermostats that drift independently. **All gas** is a gas top over a vaulted gas oven — the most mechanical range in the line, with no control board anywhere in it and nothing to read on a display because there is no display. **All induction** is the Castel 60, which is electric throughout, and any Château ordered with the all-induction cooktop — available on the 150, 120, 90 and 60 — where the ovens are always electric by rule of the order form. So the same model number can arrive as a gas range with no electronics at all or as a fully electric one where all three of this make’s error codes apply. Which of the three you have decides what can even go wrong. ### The vaulted oven is not a conventional oven with a curved roof The *voûte* is a sealed dome that cooks by radiant heat from the mass around the food rather than by blowing hot air at it, and on a Château gas oven there is no window in the door because the door is part of the mass. That has three practical consequences. Heat is delivered unevenly on purpose, so “uneven baking” on a vaulted oven is often the oven working as designed and needs a conversation before it needs a part. The gas ovens run with an electric broiler above them, so a range can lose browning and keep baking. And because there is no glass to look through, a burner that has gone out announces itself by smell and by a cold shelf rather than by sight — which is why a gas oven that will not stay lit is a same-day call rather than a next-week one. ### What South Florida does to a French range Salt air and brass are a poor combination, and a coastal kitchen with the windows open will tarnish polished trim within a season. That is maintenance rather than repair, and it is worth knowing which is which before somebody attacks a handrail with the wrong product and takes the lacquer off with the tarnish. The failures we actually get called to on ranges here are gas-side and electrical-side in roughly equal measure: igniters and thermocouples that have taken years of humidity, safety valves that no longer hold, thermostats that have drifted so gradually the owner recalibrated their own recipes instead, hob glass cracked by a dropped pan, and induction electronics that have been cooking themselves in a cabinet with too little ventilation. Every one of those is a part, not a new range. Dual fuel · gas · all-induction — Château, Châtelet, Castel, Grand Palais, CornuFé Range repair Dual fuel, all gas or all induction — three different ranges, three parts lists The configuration code, not just the model, decides what is on the top Made-to-order enamel and trim are part of the job, not an extra Nine sizes, and the configuration matters more than the size La Cornue’s current range line runs from the 23.6-inch Castel 60 to the 70.9-inch Château Grand Palais 180, with the Castel 75, Grand Castel 90, Châtelet 135, Château 120, 150 and 165 in between, and the factory-built CornuFé 90 “Albertine” and CornuFé 110 alongside them.

Every one of those is a part, not a new range. ### One oven works and the other does not. Is that one repair or two? Usually two, because on most of this line the two ovens are not the same appliance. A Château 120 and everything above it is dual-fuel by design: the left oven is a vaulted gas oven with an electric broiler, the right one is electric. They share a cabinet, a control panel and nothing else — different heat source, different thermostat, different failure list. So "the oven is not heating" is two different diagnoses depending on which door you opened, and the first question on the phone is which side. The exception is a range ordered with an all-induction top, where La Cornue's own order form forces both ovens to be electric; then the two are alike and a control failure can genuinely take both. ### How much of the range has to come apart to reach anything? Less than people fear, and that is deliberate — these are built to be serviced for decades rather than replaced. The cooktop modules lift out, the front panels come off, and most of the gas train, the valves and the igniters are reached from the front with the range where it stands. What we do not do is move it casually: a Grand Palais 180 is about 710 lb without its crate, the legs are adjustable and level to a specification, and dragging one across a tile floor to get behind it creates a bigger problem than the one it solves. When something genuinely requires access from behind, that is planned, with the right number of people and the right equipment. ### The enamel is chipped near a burner. Can that be repaired or is it cosmetic? Treat it as neither cosmetic nor hopeless. Vitreous enamel is glass fused to steel, and once it is broken the steel underneath is exposed to moisture and cooking acids, which in this climate means it will rust from the chip outwards. Small chips in a low-heat area can be stabilized. A chip on a drip tray or directly under a burner is in the worst possible place and the honest answer is a replacement part in the original color, ordered against the range's own finish. That is a reason to tell us the finish name when you call rather than after the visit — a color match on this make is a catalog reference, not a judgement made by eye. ### It was converted to propane years ago and now the flames look wrong. Related? Very possibly, and it is one of the first things we check on a range that has moved house or changed fuel. La Cornue publishes a conversion procedure and a specific set of parts for the CornuFé 90 and 110; a Château is specified for natural gas or propane at the time of order, and altitude above 2,000 feet is specified too. A conversion done with approximate parts, or a range plumbed for one fuel and fed the other, gives exactly what you are describing: lazy yellow tips, soot on a pan bottom, burners that will not hold a low flame. Bring us the conversion paperwork if it exists, and if it does not, say so — that is useful information rather than an admission. --- **[Read full article: Ranges](https://la-cornuemiami.support/appliances/range/)**
