La Cornue appliance maintenance
An annual visit that exists because most of what goes wrong on this make goes wrong slowly. Burners drift rich, thermostats drift hot, baffles saturate, brass tarnishes, and the owner adapts to every one of them without noticing. This is the visit that measures instead of adapting.

On the visit
How this visit actually goes
The same order every time, so nothing is opened and nothing is charged before you have seen the figure and said yes.
-
01
Combustion across every burner
Flame color, port condition, air mix. A rich burner sooting a pan bottom is a five-minute adjustment now and a cleaning job later.
-
02
Oven calibration, both sides
A probe on the shelf through a full cycle. On a dual-fuel range that is two measurements, because the gas oven and the electric oven drift independently.
-
03
The hood, properly
Baffles out and washed, duct flow checked, blower current measured. This is where an annual visit pays for itself in a kitchen that cooks.
-
04
Seals, hinges and the door pull
The parts that fail so gradually that the owner adapts. Measured against specification rather than opinion.
-
05
Enamel, trim and the underside of the French top
Chips found while they are still stabilisable, and rust found before it is through the iron.

Dual fuel · gas · all-induction — Château, Châtelet, Castel, Grand Palais, CornuFé La Cornue range repair in Miami
The range is what La Cornue makes, and everything else in the line exists around it. A Château is built to order in France, arrives in a crate weighing over half a ton, and is assembled from parts a customer chose one at a time: which oven is gas and which is electric, whether the top carries a French top, a lava-rock grill, induction or a teppanyaki plate, which of about fifty enamels, which trim metal. Two of them are almost never identical. That is the first thing a repair on one has to take seriously — the model number tells you the size, and the configuration code tells you what is actually under the lids.
- 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

Vaulted ovens and convection ovens — gas, electric, and the Tourelle wall oven La Cornue oven repair in Miami
There are three different ovens on this make and they fail in three different ways. The vaulted gas oven cooks by radiant heat inside a sealed dome and has an electric broiler over it. The vaulted electric oven sits on the other side of the same range. And since 2025 there is a standalone one: the Château Tourelle, a fully electric multifunction wall oven in 60 and 75 centimeter widths, built to sit in a cabinet run next to a Château cooktop. Which of the three you have decides everything about the repair.
- Vaulted gas, vaulted electric and the electric Tourelle wall oven
- Gas ovens carry an electric broiler — browning and baking can fail separately
- Thermostat drift is measured against a probe, never adjusted by feel

Brass gas burners · plaque coup de feu · lava-rock grill · induction · teppanyaki La Cornue cooktop repair in Miami
A La Cornue cooktop is a set of modules chosen at order time and dropped into a stainless frame: brass gas burners at 17,000 and 7,500 BTU, a 22,000 BTU power burner, the cast-iron plaque coup de feu heated by a single burner underneath, a lava-rock grill, ceramic-glass induction zones, an electric teppanyaki plate. This is the top of a range, and each module is a different repair. Sold on its own without ovens beneath it, the same top is a rangetop, and it has its own page.
- Gas, induction, French top, grill and teppanyaki modules on one frame
- Induction is the only half of this line that shows a code — E2, U400, Er
- A cracked glass hob is disconnected first and diagnosed second
-
T40 to T48 · 200 mm into the counter · the same modules, no ovens beneath La Cornue rangetop repair in Miami
A rangetop is the top half of a La Cornue sold in its own right: the same brass burners, the same plaque coup de feu, the same grill, induction and teppanyaki modules, in a stainless frame 200 mm deep that drops into a counter with nothing underneath it. T40 through T48, from 600 to 1800 mm wide. Every cooktop repair applies to it and no oven repair does — which makes it the simplest appliance in the line and the one most often confused with the range on a booking.
- T40 to T48 — the same configuration codes as the range
- No ovens, no oven thermostats, no door seals
- Much lighter than a range, so the one job that prices weight rarely applies

Château motorized hoods H11–H20 · island hoods · inserts · CornuFé Cascade, Euclid, Loge, Marquee La Cornue range hood repair in Miami
The hood over a La Cornue is not an accessory bought to match. A motorized Château hood starts at $17,400 for the 90 and runs past $25,000 for the Grand Palais 180, it is made in the same enamels and trims as the range, and it does real work: a 600 CFM blower on a four-speed variable motor, baffle filters with a grease capture system, three 20-watt lights and a remote. When one stops, the kitchen it was built for stops working properly.
- Motorized Château hoods, island hoods and inserts, plus the CornuFé collection
- 600 CFM blower, four-speed variable motor, baffle filters, remote control
- A hood is finished to match the range — the enamel is part of the repair

About La Cornue appliance maintenance
About maintenance on a hand-built French range
Most of what goes wrong here goes wrong slowly enough that the owner adapts instead of noticing. Burners drift rich, a thermostat drifts twenty-five degrees over three years, baffles saturate and halve the extraction, brass tarnishes, and a chip in the enamel starts rusting under the surface. An annual visit measures all of that against specification rather than against memory: combustion on every burner including the plaque and grill burners, both ovens calibrated with a probe through full cycles, the hood's baffles and duct and blower, and the finish inspected while a chip is still stabilisable.

Questions about La Cornue appliance maintenance
How long does it take?
On a Castel 75 with a hood, a couple of hours. On a Grand Palais 180 with two ovens, a plaque, a grill and a motorized hood, most of a morning — and the figure says so rather than hiding the time somewhere else. We would rather book the right amount of time once than come back.
Do you clean the range as part of it?
We clean what has to be clean for the appliance to work: burner ports, caps and crowns, the plaque and its underside, the baffles and capture tray, and the air path under an induction top. That is not a valet, and we will say plainly that it is not. What we will do is tell you which products are safe on your particular finish and trim, which is the part people most often get wrong on their own.
