La Cornue
Southern California
01, the brand
A La Cornue is the one appliance in the kitchen with no computer in it — which is why nothing you find online about fixing it is any use.
Search any other luxury range and you get fault codes. Wolf gives you an Err. Thermador gives you an E-something. Gaggenau gives you a display. Search La Cornue and you get pages that look like all the others — same layout, same promises, same vague list of "common issues" — because the companies writing them ran the same template they run for every brand. The template doesn't fit. La Cornue ranges have no error-code system at all. Not a hidden one, not a service-mode one. None.
We know that because it's in the manuals. The CornuFé manual says outright that no error or fault codes are present, and organises its troubleshooting by symptom instead — burners faulty, steam from the oven, food cooking slowly. The Château G4 manual does the same. There's no clock on these ranges, no timer, no Wi-Fi, no display to put a code on. The single indicator light you'll find is on the gas-oven safety device, and it's a light, not a message.
That changes how the visit goes. Our techs turn up with a manometer and a multimeter and read the range the way you'd read a car from before OBD-II: watch the flame, test the thermocouple, check the thermostat against an independent probe, look at what the burner is actually doing rather than what a screen claims it's doing. It's slower to explain and faster to fix, and it's the reason a 1990s Château and a range delivered last month fail in recognisably the same ways.
The brand is Parisian, founded in 1908 by Albert Dupuy — a perfumer, not an engineer — who started building ovens when natural gas arrived in Paris. The Dupuy family ran it for generations. Ownership since has moved through the AGA Rangemaster group and then Middleby, and on 2 February 2026 it moved again: 26North Partners bought 51% of Middleby's residential kitchen business in a deal valuing it at $885 million, Middleby kept a 49% non-controlling stake, and the group was renamed Composition Brands. La Cornue sits in that portfolio now alongside Viking, AGA, Rangemaster, Lynx, U-Line and Marvel. Worth knowing if you're chasing a warranty or reading an older page that still calls it a Middleby brand — most of the internet hasn't caught up. Irrelevant to the burner in front of you, which hasn't changed.
02, the split that matters
Château or CornuFé — same badge, two completely different repairs.
This is the first question we ask on the phone, and no competitor page in Los Angeles explains why it matters.
Château — hand-built in France
Made to order in the workshop at Saint-Ouen-l'Aumône outside Paris, by a shop of roughly sixty craftsmen. Six sizes from about 29.5 inches up to the 71-inch Grand Palais 180, around 8,000 possible configurations, 48 colours, six trims. Roughly $27,500 to past $60,000 depending on the build.
What that means for service: your range is a configuration, not a model number. We need the serial plate before ordering anything, because two Châteaux of the same width can take different parts. Wear items are straightforward. Bespoke items — an enamelled panel in a colour that's no longer offered, brass trim matched to your build — are a conversation, not a next-day part.
CornuFé — factory-built in England
Built at an AGA Rangemaster facility in Birmingham, standardised rather than bespoke. Two sizes, roughly 35.4 and 43 inches (the 90 and 110 you'll see quoted), twelve colours, three trims. Roughly $8,475 to $11,700. Fan-forced electric convection in the oven.
What that means for service: a CornuFé behaves like a normal appliance. Parts map to a model, the convection fan and element are conventional components, and sourcing is predictable. If you've been told your CornuFé needs the same treatment as a Château, you've been told wrong.
Grand Palais 180 — a model, not a line
Worth correcting, because it's wrong nearly everywhere: the Grand Palais 180 is the 71-inch flagship within the Château series, not a separate product line. If a company tells you they service "the Grand Palais line," they're reading a spec sheet they don't understand.
Flamberge — a rôtisserie, not a range
Also routinely miscategorised. The Flamberge is a 30-inch wall-mounted gas rôtisserie — a cast-iron concave back wall, a gas burner beneath three motorised spits, no flue required. It is not a range and doesn't share a range's failure modes. We service the burner, the spit motors and the gas train.
03, scope
La Cornue makes cooking appliances. That's the whole catalogue.
Ranges, matching range hoods, the Flamberge rôtisserie, kitchen furniture and accessories. That's it. No refrigerators. No dishwashers. No washers or dryers. We're stating it flatly because people search for La Cornue refrigerator repair every month, and the pages that rank for it quietly take the call instead of correcting the premise.
So if you have a La Cornue kitchen and the fridge has stopped, the fridge is another brand — usually Sub-Zero in this class of build, sometimes Liebherr, occasionally True Residential behind a custom panel. All of those we do service; tell us what's on the model plate when you call, or send a photo of it, and we'll arrive with the right parts instead of the right brochure.
One honest caveat on how we know: this is evidenced by what's absent from La Cornue's own catalogue and from every dealer catalogue we checked, not by the manufacturer publishing a denial. It's a strong and consistent signal rather than a quoted statement, and we'd rather tell you which kind of fact it is.
04, what actually fails
Mechanical ranges fail mechanically — here's what we're looking at.
A note on what follows. Every other brand page on this site carries dated job stories with model numbers and neighbourhoods. There isn't one here, and that's deliberate: we're not going to invent La Cornue service records to make the page look busier. What we can tell you honestly is what these ranges do when they go wrong, and how the diagnosis runs when there's no code to read.
Burner won't light, or won't stay lit
On a gas range with electric ignition, this splits three ways: the igniter itself, the thermocouple or flame-supervision device that tells the gas valve the flame exists, or the gas train. The tell is in the behaviour — clicks with no flame, flame that dies the moment you release the knob, flame that lights and drops a minute later. Each points somewhere different. All three are wear items and all three are serviceable.
Oven won't hold temperature
With no digital readout you can't trust the dial to tell you the truth, so the first thing our techs do is put an independent probe in the cavity and see what the oven is actually doing versus what the thermostat thinks. Drift usually lands on the thermostat or, on a CornuFé, the convection fan and element circuit. A Château's gas oven and a CornuFé's fan-forced electric oven behave differently enough that the same complaint has different answers.
Red light on the oven safety device
The one indicator these ranges have. It's a gas-oven safety device signal, not a fault code, and it doesn't tell you which component is unhappy — it tells you the safety circuit has intervened. Diagnosis from there is by test, not by lookup.
Doors, seals and the heavy hardware
These are seriously heavy ranges with substantial doors. Hinges, door seals and the closing mechanism take real load over decades, and a door that no longer seals shows up first as an oven that can't hold heat — which people reasonably misread as a thermostat problem. Worth checking before anyone orders a part.
Knobs, trim and the cosmetic layer
On a range where the finish is the point, a cracked knob or damaged trim is a real repair, not a cosmetic afterthought. This is also where the Château/CornuFé split bites hardest: a CornuFé knob is a part number; a Château knob in a discontinued colour is a hunt.
What we won't do
Guess at a code that doesn't exist, or quote you a part before we've seen the serial plate on a Château. If someone has handed you a La Cornue fault-code table, they made it up.
The vaulted oven deserves its own note, because it's the thing that makes a Château a Château and it changes how a temperature complaint gets diagnosed. The oven roof is curved rather than flat, and the design intent is that heat circulates around the vault by convection — no fan doing the work. That's why a Château bakes the way it does, and it's also why "the oven is uneven" needs care before anyone touches a thermostat. A vaulted gas oven is supposed to have a gradient; that's the point of it, and cooks who came from a fan oven sometimes read the feature as a fault. What isn't normal is drift over time, a cold spot that wasn't there last year, or an oven that won't reach temperature at all. The first thing we do is establish which of those we're looking at, with a probe rather than an opinion.
Hoods are the quiet half of the service load. La Cornue's matching ventilation is built to sit with the range as one composition, and when a hood fails, the failure is usually mundane — fan motor, switch, or lighting — even though the panel it lives behind is anything but. The parts logic follows the same France-versus-England split as the ranges do, so we scope hood work the same way: identify the build first, source second. That work has its own page in more depth at La Cornue range hood repair.
05, parts and the factory channel
Where La Cornue parts actually come from — and when you should call the factory instead of us.
If your range is in warranty, use the factory channel. La Cornue USA runs a Find-a-Servicer locator and a parts-and-service channel, and Purcell Murray has been the American distributor for the brand for over thirty years. Going outside that while you're covered can cost you the coverage. We'd rather tell you that and lose the call than take it and cost you a warranty on a $40,000 range.
We're independent — not factory-authorized, and we say so plainly. Where that's useful is everything after the warranty: out-of-warranty Châteaux, CornuFés whose original dealer has moved on, ranges that came with a house and no paperwork, and the calls where you'd like someone this week.
On lead times, we'll give you the structure rather than a number. You'll find competitor pages asserting six months or more; that figure isn't sourced to anything and we're not going to repeat it as though it were. What's verifiable is that there's no US manufacturing — Châteaux are built to order in France, CornuFés come from the UK factory. Wear items are usually obtainable through the US channel. Bespoke enamelled and brass components are genuinely open-ended. We quote the part and the wait before you commit, and if the wait is unreasonable we say so.
One more thing worth knowing while you're shopping around. Several of the sites ranking for La Cornue repair in Los Angeles are .support domains built to look like the manufacturer, naming no operator and claiming to be "certified" without saying by whom. We're BHGS #A49573, we're independent, and our name is on the invoice.
06, repair or replace
On this brand it isn't a close call.
Most of the time, repair-versus-replace is a real conversation and we walk customers through the maths honestly — a twelve-year-old mass-market fridge with a failed compressor is usually a replacement, and we'll tell you so. La Cornue is the opposite case, and it's not close.
A Château starts around $27,500. A Grand Palais 180 configuration runs past $60,000. And because they're made to order, replacing one isn't something you do this month even if you want to. Against that, what fails is wear: thermocouples, igniters, thermostats, seals, hinges, knobs, burner components. The mechanical simplicity that makes these ranges impossible to search for is exactly what makes them repairable for decades. There's no control board to be discontinued, no proprietary diagnostic module to go obsolete, no firmware to stop being supported. That's the quiet advantage of buying a range with no computer in it: it can't be orphaned by a software decision.
07, the other French range
La Cornue or Lacanche — they get confused constantly, and they're not the same thing.
If you own one you already know the difference. If you inherited one with a house, you may not, and it matters when you're booking a repair. Both are French, both are heavy, both are enamel-and-brass, both are all-analogue with no error codes. They are different companies.
La Cornue is Parisian, founded 1908, and the Château is built to order at Saint-Ouen-l'Aumône. Lacanche comes from the village of Lacanche in Burgundy, a different firm with a different history and a different parts channel. A tech who knows one does not automatically know the other, and the parts are not interchangeable in any respect.
Telling them apart on sight is easy once you know: La Cornue's signature is the vaulted oven — a curved oven roof designed to circulate heat convectively without a fan — and on the Château the brass trim and the bullnose rail are the visual tell. Lacanche runs a flatter, more austere line. If you're not sure which you have, send us a photo of the badge and the control panel before we come out; it decides which parts channel we're working through, and on these ranges that's most of the job.
One more pairing worth naming, since the ownership story runs through it: AGA sits in the same corporate portfolio as La Cornue today, and CornuFé ranges are actually built in an AGA Rangemaster facility in England. So the CornuFé in your kitchen has more manufacturing DNA in common with an AGA than with the hand-built Château wearing the same badge. That's not a criticism — it's a well-made range — but it's the sort of thing you want your technician to already know.
08, before you call
What to have ready — it genuinely changes the visit.
On most brands "have your model number" is a formality. On La Cornue it decides whether we can help you this week.
The serial plate, photographed
On a Château the serial is the whole story. Because each range is configured individually out of roughly 8,000 possible combinations, the serial is what tells us your burner layout, your oven configuration, your trim and your colour. Two 43-inch Châteaux built a year apart can take different parts. A photo of the plate beats a model number read over the phone.
Château or CornuFé — say which
France or England, bespoke or standardised, gas oven or fan-forced electric. It determines the parts channel and often the diagnosis. If you don't know, the size is a clue: a 35.4 or 43-inch range is almost certainly a CornuFé; anything at 29.5, 59 or 71 inches is a Château.
What the burner is actually doing
With no code to read, your description is the diagnostic. Does it click and not light? Light and die when you release the knob? Light and drop out a minute later? Burn yellow instead of blue? Each points somewhere different, and describing it accurately on the phone often means we arrive with the part already on the van.
Whether it's in warranty
If it is, we'll tell you to call the factory channel instead of us. La Cornue USA runs a Find-a-Servicer locator and Purcell Murray distributes the brand in the States. We'd rather send you there than cost you coverage on a range worth more than a car.
09, coverage
La Cornue service across Greater Los Angeles.
The La Cornue calls cluster where the kitchens are: Bel Air, Beverly Hills, Holmby Hills, Brentwood, Pacific Palisades, Malibu, the hillside remodels above Sunset, the newer estate builds out in Hidden Hills and Calabasas. We run into Ventura County for the coastal addresses and down into Orange County for Newport and Laguna.
Same-day is realistic across the Westside. Further out, we'll tell you honestly on the phone whether it's today or tomorrow rather than booking a window we can't hold. Call (424) 325-0520 with the model and serial off the plate — on a Château the serial is what matters, because your configuration determines your parts.
10, FAQ
La Cornue repair, common questions.
What La Cornue error code am I looking at?
There isn't one. La Cornue ranges have no diagnostic error-code system — and that's not us being unhelpful, it's how the ranges are built. The CornuFé owner's manual states plainly that no error or fault codes are present, and the Château G4 manual organises its troubleshooting by symptom rather than by code. There's no clock, no timer, no Wi-Fi module and no display to put a code on. The one indicator you may see is a red light on the gas-oven safety device — that's a light, not a code. So if you're searching for a La Cornue fault-code table, every result you find is either about a different brand or invented. Diagnosis here is done the old way: by symptom, by flame behaviour, by thermocouple and thermostat testing on-site. Our techs bring a manometer and a multimeter, not a code reader.
Do you repair La Cornue refrigerators?
La Cornue doesn't make refrigerators, so no. This comes up often enough that it's worth stating plainly: La Cornue builds cooking appliances only — ranges, matching range hoods, the Flamberge wall rôtisserie, plus kitchen furniture and accessories. No refrigerators, no dishwashers, no washers or dryers. Their official catalogue and every dealer catalogue we've checked lists cooking equipment exclusively. If you have a La Cornue kitchen, the refrigeration in it is another brand — very often Sub-Zero, sometimes Liebherr or True Residential in the same class of build. We service all of those, so tell us the make on the fridge when you call and we'll bring the right parts. If you're not sure what it is, send a photo of the model plate.
What's the difference between a Château and a CornuFé — and does it change the repair?
It changes almost everything about the repair. The Château is the hand-built line: made to order in La Cornue's workshop at Saint-Ouen-l'Aumône outside Paris, roughly 8,000 possible configurations across six sizes from about 29.5 inches to the 71-inch Grand Palais 180, in 48 colours and six trims. Prices run from roughly $27,500 to north of $60,000. Because each one is configured individually, parts are matched to your specific build, not pulled off a shelf by model number alone — we need the serial plate before we order anything. The CornuFé is the standardised line, factory-built in England at an AGA Rangemaster facility in Birmingham, in two sizes (about 35.4 and 43 inches), twelve colours and three trims, roughly $8,475 to $11,700, with fan-forced electric convection. CornuFé parts behave like normal appliance parts. Château parts behave like French coachwork. Same badge, two genuinely different service realities — and no competitor page in Los Angeles explains this.
Are you a La Cornue authorized service center?
No — we're independent, and we'd rather say so than imply otherwise. La Cornue USA runs its own Find-a-Servicer locator and a parts-and-service channel, and Purcell Murray has been the American distributor for the brand for over thirty years. If your range is inside its warranty period, use the factory channel — that's the honest advice, and going outside it can cost you the warranty. Where we're useful is everything after that: out-of-warranty Châteaux, CornuFés whose original dealer has moved on, second-owner ranges that came with the house, and the calls where you want someone this week rather than next month. Worth knowing when you're searching: several of the sites ranking for La Cornue repair in LA are brand-mimicking .support domains that name no operator and claim to be "certified" without saying by whom. Ask any company you call who they actually are.
How long do La Cornue parts take?
Longer than a Wolf or a Thermador, and we won't pretend to a number. You'll see competitor pages assert "six months or more" — that figure isn't sourced to anything, and we're not going to repeat it as if it were. What we can tell you is the structural reason, which is verifiable: there is no US manufacturing. Châteaux are built to order in France, CornuFés come from the UK factory, and consumables move through the US distribution channel rather than sitting in an LA warehouse. In practice that means the wear items — thermocouples, igniters, burner caps, knobs, door seals, oven thermostats — are the ones worth sourcing and are usually obtainable; and the bespoke items, enamelled panels in a discontinued colour, brass trim matched to a particular build, are the ones where the answer is genuinely "we'll find out." We quote the part and the wait before you commit, and if the honest answer is that the wait is unreasonable we tell you that too.
Is it worth repairing a La Cornue, or should I replace it?
Repair. On this brand the maths isn't close, and it's the rare case where we don't have to think about it. A Château replacement starts around $27,500 and a Grand Palais 180 configuration runs past $60,000 — and because they're made to order, replacement isn't a weekend errand even if you want one. Against that, the failures we deal with on these ranges are wear items: thermocouples, igniters, thermostats, seals, knobs, burner components. The mechanical simplicity that makes them frustrating to search for online is exactly what makes them repairable for decades — there's no control board to be discontinued, no proprietary diagnostic module to go obsolete, no firmware. A 1990s Château and a 2024 Château fail in recognisably the same ways. That's the upside of buying a range with no computer in it.
What does La Cornue repair cost in Los Angeles?
Our diagnostic is $89, and it comes off the bill the moment you approve the repair. Beyond that we quote per job rather than publishing a rate card for this brand, and the reason is honest: the spread between a CornuFé thermocouple and a Château part matched to a bespoke build is wide enough that any "typical price" we printed would be misleading for half the people reading it. What we will commit to: you get the part price and the labour before we start, and what we quote is what appears on the invoice. Call (424) 325-0520 with the model and serial off the plate — on a Château it's the serial that matters, because the configuration is what determines the part.
Which parts of Los Angeles do you cover for La Cornue?
All of it, and the La Cornue calls cluster where you'd expect — Bel Air, Beverly Hills, Holmby Hills, Brentwood, Pacific Palisades, Malibu, plus the hillside remodels above Sunset and the newer estate builds in Hidden Hills and Calabasas. We also run out to Montecito-adjacent Ventura County addresses and into Orange County for the Newport and Laguna coastal builds. Same-day is realistic across the Westside; further out we'll tell you honestly whether it's today or tomorrow when you call rather than booking a window we can't hold.
