La Cornue repair in Key Biscayne
An island reached by one causeway, with salt air on both sides of it. Corrosion, and appliances that will not restart cleanly after an outage, are the two calls we take most often here.
We cover Key Biscayne and the rest of Miami-Dade: an on-site diagnostic first, the price agreed in writing before anything is opened, and the exact figure confirmed once we have seen the unit.

What we repair in Key Biscayne, by La Cornue unit
Start with whichever matches yours. How an appliance is installed shapes the visit as much as the repair does, which is why we ask about it when you book.

Dual fuel · gas · all-induction — Château, Châtelet, Castel, Grand Palais, CornuFé La Cornue range repair in Key Biscayne
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 Key Biscayne
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 Key Biscayne
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 Key Biscayne
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 Key Biscayne
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
By job
The repairs we are called out for in Key Biscayne
Starting figures for this equipment in South Florida. What moves them is the model, the access and the part — the exact cost is confirmed after the on-site diagnostic.
-
from $165 Hood lighting and remote repair
Three 20-watt high-intensity lamps on the Château hoods, LEDs on the newer inserts, and two separate control paths — in-hood activation and a remote. A hood that answers its own buttons but not the remote is a receiver, not a motor.
- Single lamps are often a customer job and we say so
- Remote and in-hood controls tested as separate paths
- Two or three lamps out at once is a socket or supply problem, not bulbs
-
from $155 Surface burner and igniter service
Clicking with no flame, a burner that lights and will not stay lit, a lazy yellow flame. On brass burners in a coastal kitchen these are three symptoms of a short list of causes, and none of them is the ignition module when only one burner is affected.
- One burner out is the electrode or the ports — not the module
- Yellow flame is air mix, fuel or an orifice, and it is measurable
- Ports cleared properly rather than poked at
-
from $325 Propane conversion service
La Cornue publishes a conversion procedure and a specific parts set for the CornuFé 90 and 110, and specifies fuel at order time on a Château. A conversion done with approximate parts gives yellow flames, soot and burners that will not hold a simmer — and it is one of the most common things we undo on a range that has changed house or fuel.
- The maker's own orifice set, not a universal kit
- Every burner and both ovens set and verified, not just the fronts
- Written record of what the range is now set for
-
from $185 Oven thermostat calibration
An oven that has drifted hot over years, and a cook who has quietly rewritten every recipe around it. The manual is explicit: an oven that gets hotter as the range ages and does not come back when the dial is turned down wants a thermostat, not a new habit.
- Measured with a calibrated probe through a full cycle
- Drift distinguished from a vaulted oven's designed unevenness
- The owner warned that a corrected oven changes their cooking
-
from $325 Induction hob repair
The three codes La Cornue documents anywhere all live here: E2, the electronics are too hot; U400, the cooker is incorrectly connected; Er with a number, an internal problem the user cannot clear. Everything else on that display is an indicator, and telling the two apart saves a visit.
- E2 is investigated as ventilation first, as the maker's own guide says
- Indicators — H, the pan-missing symbol, L, A, P — are not problems
- Zone-by-zone testing with pans that meet the minimum diameters
-
from $175 Hood filter and duct service
Faded suction with a motor that still sounds fine is almost never the motor. Baffle filters with a grease capture system are dishwasher safe, and the 600 CFM figure is specified against an unobstructed six-inch duct — eight on the inserts. Most of this job is the air path.
- Baffles cleaned or replaced first, because it costs nothing to rule out
- Duct run, damper and termination measured rather than assumed
- Airflow verified after the work, not promised

What La Cornue equipment is like in Key Biscayne
An island reached by one causeway, with salt air on both sides of it. Corrosion, and appliances that will not restart cleanly after an outage, are the two calls we take most often here.
Key Biscayne sits in Miami-Dade County, and the equipment here follows the housing: older kitchens with appliances fitted into openings that were cut for something else, and newer ones where they were specified with the cabinetry. Both are La Cornue work — cooktops and rangetops, ovens, range hoods — and both are diagnosed on site before anything is priced.
Salt, heat and storms — what they do to burners and vents
Close to the water it is the steel and the ignition that go first. Salt reaches burner caps, grates and igniter electrodes, and an igniter that has to spark through corrosion is an igniter that clicks and does not light. Ventilation suffers with it: a hood that pulls salt air through its motor every day is on a shorter life than the one the manufacturer costed. In Key Biscayne that is the difference between an annual clean and a seasonal one.
What that means for the appliances in Key Biscayne
- Range hoods — Salt reaches the far end of a duct before it reaches anything in the kitchen. A wall cap with a corroded damper that no longer opens leaves a smoky room behind a hood that sounds perfectly healthy.
- Cooktops and rangetops — Burner caps, grates and igniter electrodes take the salt here. An igniter sparking through corrosion is an igniter that clicks and does not light, and it happens on a shorter schedule near the water.
- Ranges — Stainless that would stay clean inland pits within sight of the water, and the parts that suffer are the ones nobody looks at — burner caps, grate feet, the fixings behind a control panel.
- Yellow or orange flame
- Burner will not stay lit
- Weak or uneven flame
- Gas smell in the kitchen
- Stiff or stuck burner knob
How a visit in Key Biscayne is arranged
We ask for the model number from the plate inside the door and a line about what the appliance is doing. That decides which parts ride in the van, and it is the difference between one appointment and two.
- In a building: the service elevator window, the loading bay and the hours contractors are allowed to work
- Behind a gate: how visitors are cleared, arranged before the appointment rather than at it
- Whether the gas is propane or natural, which decides the orifices and the parts that ride in the van
- The diagnosis first, then the scope and the price in writing, and your approval before anything is opened
What it costs, and what moves the figure
Prices in Key Biscayne are the same as everywhere else we cover: a diagnostic from $95 that is credited toward the repair, and starting figures per job rather than one number for "a repair". What moves it is the model, how the appliance is built into the cabinetry, which part it needs and how quickly that part can be sourced — none of which can be judged over the phone. The repairs we carry out lists what each job involves and the figure it starts at, and the unit pages covers what tends to go wrong on each type.
The exact cost is confirmed after the on-site diagnostic and agreed with you before any work begins. We are an independent repair company — not affiliated with, authorized by, or endorsed by any manufacturer — and our warranty covers the labor we performed.
Before you book
Questions about a visit in Key Biscayne
Do you cover Key Biscayne?
Yes. Key Biscayne is in Miami-Dade County and inside the area we work every week. Give us the address when you book, and say how the La Cornue is installed — what has to come apart to reach it matters as much as where it is.
How soon can you get to Key Biscayne?
We will tell you the earliest slot we can genuinely keep rather than the earliest one that sounds good. Tell us the model number and what the unit is doing when you book: whether we can finish the same day depends on the part far more than on the drive.
Does it cost more because the job is in Key Biscayne?
No. The diagnostic and the work are priced the same across Miami-Dade, Broward and Palm Beach. What moves the figure is the model, how the unit is built in and which part it needs — never the address. Where access takes longer, we say so before anything is agreed rather than after.
Does getting to Key Biscayne change the visit?
It changes the planning rather than the price. A visit here is scheduled rather than fitted in, and we bring the parts the symptom usually needs — a second trip costs a day here instead of an hour.
Booking a visit in Key Biscayne
Tell us the model number and what the unit is doing. We will bring the parts that problem usually needs, and you will have a firm price before we start.
