La Cornue diagnostic visit
One visit, one technician, one answer in writing. On a make with three error codes in its entire documentation, the diagnostic is not a formality before the repair — it is the repair's only source of information, and it is done with instruments rather than by elimination.
- From $95 diagnostic, credited to the repair
- 59 cities and neighborhoods covered
- OEM parts available on order
- In writing the price, before anything is opened
Before you read on
What this job costs and how it is agreed
A starting figure, not a quote. What moves it is the model, how the unit is built in and which part it needs — settled after the on-site diagnostic.

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
Read the range, not just the badge
Size, model code and the top configuration. A Château 150 in a K3 configuration and the same range in a K6 need different parts for the same complaint.
-
02
Hear the history
When it started, whether it was sudden or gradual, what changed in the kitchen. A fuel conversion, a moved range or electrical work upstream explains a large share of these calls.
-
03
Measure what can be measured
Gas pressure at the manifold, element resistance, actual shelf temperature against the dial, supply voltage at the appliance. Numbers, in the report.
-
04
Separate the design from the problem
A vaulted oven cooks unevenly by design and an H on the induction display means residual heat. Some calls end here, and that answer is worth the visit.
-
05
Price it before touching it
Parts, lead time and labor in writing. Nothing is opened, ordered or fitted until it is agreed.

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 diagnostic visit
About a diagnostic visit on a La Cornue
This make tells you almost nothing about itself. Three error codes exist in the whole of La Cornue's US documentation and all three are on the induction hob, so on a gas Château the visit is the only source of information there is. It opens by reading the range rather than the badge — size, model code and the top configuration, because two ranges with one model number can hold different modules — then measures: gas pressure at the manifold, igniter current, shelf temperature against the dial, supply voltage at the appliance. It ends with numbers, a recommendation and a from-price in writing, and the fee comes off the repair.

Before you book
Questions about La Cornue diagnostic visit
What should I have ready when I book?
The size and the model code if you have them — G45, T49, C1-I and so on — plus the top configuration code if the paperwork survives, and the finish name. Those four things decide which parts travel with us. Then the ordinary questions: what it is doing, when it started, and whether anything changed in the kitchen recently.
Where is the data plate on a La Cornue?
On the Château ranges it is usually behind the lower door or on the frame at the side of the oven aperture; on a CornuFé it is on the frame behind the door. Photograph it rather than copying it down. If you cannot find it, the original invoice or the dealer's order confirmation is genuinely more useful on this make than on any other, because it carries the configuration and the finish reference as well.
