La Cornue french top service
The plaque coup de feu is a single cast-iron plate heated by one 7,500 BTU burner directly under its center, and it is the most-used and least-understood part of the range. Cracks, warping, rust, dead cold spots and a burner running wrong underneath are all different problems that present the same way.

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 plate
Where the heat actually is, with the burner running. The center is meant to be hottest; a cool center is a burner problem, not a plate problem.
-
02
Crack or crazing
One is cosmetic and one changes how heat crosses the iron. This is the question the whole visit turns on.
-
03
The burner and the drip area underneath
A rich flame or a blocked drip tray puts more heat into one spot than the plate spreads.
-
04
Rust and the underside
The side nobody looks at, and the side that rusts first in this climate.
-
05
Season and hand it back
A stripped or rusted plate is cleaned back and re-seasoned, and the owner is told how to keep it that way.

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

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

About La Cornue french top service
About the plaque coup de feu
A single cast-iron plate heated by one 7,500 BTU burner directly beneath its center, and the most-used, least-understood part of the range. It is meant to be uneven — hottest above the burner and cooler as you work outwards, which is how you cook on one — so the first question on this visit is what the owner expects, and a proportion of them end in a demonstration rather than a repair. Where there is a real problem it is usually the burner underneath, then the underside of the plate, then the air path, then the seating, and only then the iron.

Questions about La Cornue french top service
What temperature should the center reach?
Hot enough to sear directly on the iron after a proper preheat, with a usable simmer at the outer edge. We measure rather than quote one number, because the honest figure depends on the plate size, the fuel and how long it has been up. What matters diagnostically is the gradient and the ceiling: a plate whose center now tops out where its mid-zone used to be has lost its burner, not its iron.
Does seasoning affect the heat?
Not measurably. What does insulate is the opposite — rust and baked-on carbon, particularly on the underside where nobody looks. Cleaning that face back and re-seasoning the top is part of the service, and we will show you how to keep it rather than leaving you to guess.
