What we can tell you
What this number means for a repair
Not a specification table. Capacity, dimensions and production years are not something we can verify, and a plausible-looking table of them would be invention rather than information.
-
The full number is the first thing we ask for
It decides what the display can tell you and how easily parts are found, and the data plate settles it in one line. Letters after the digits are not decoration — they identify the configuration, and two units sharing the digits can take different components.
-
What we ask you to read off the unit
The data plate, not the crate or the invoice. On this equipment it is inside the appliance rather than on the outside of it: on a range, open the oven door and look along the inside of the frame or behind the plinth at the bottom; on a rangetop, lift a burner grate and look at the deck below it; on a wall oven it is on the door frame. It carries the full number and the configuration code together, and a photograph of it is worth more than any table we could publish.
What owners of this model ask about
The symptoms searched most often with the T40USAA
Taken from real search suggestions rather than from a list we made up. Each page says what the symptom usually points at and what to check first.
-
One zone does nothing Induction zone not heating
Before this is a problem it is worth ruling out the two things that are not: a pan that is not induction-compatible, and a pan whose base is smaller than the minimum for that zone. La Cornue publishes those minimums, and a small pan on a large zone will not couple at all — the cooktop is behaving exactly as designed.
- Minimum pan base: 4¾ in front left, 5½ in rear, 8¼ in center
- The pan-missing symbol is an indicator, not a problem
- One dead zone with the others fine is a coil or a sensor
-
It cuts out under load Induction shows E2 and shuts off
E2 is one of three codes La Cornue prints anywhere in its US documentation, and the manual's own explanation is specific: the electronic unit is too hot. Its first suggestion is not a part — it is to check the installation of the cooker and whether there is sufficient ventilation.
- The maker's own first answer is ventilation, not electronics
- A pan boiled dry produces it too
- Resetting it and carrying on is how a generator board dies
-
Stop using it now Cracked induction glass
This is the one problem on this appliance with a safety instruction attached, and La Cornue's own guide is unambiguous about it: disconnect the cooker from the power supply immediately and do not use it until it has been repaired. The glass is what separates the coils and the electronics from anything spilled on the surface.
- Disconnect it at the supply — the maker says so, not us
- Do not cook on it, even on the zones that still work
- The replacement panel is ordered to that top's own zone layout

About La Cornue T40USAA repair
What this model is
Castel 60 Rangetop, also printed as Château Rangetop 60 — a the Castel 60 rangetop — all-induction, four zones. 600 mm, 23.6 inches, about 121 lb uncrated and 165 lb crated. A large induction hob with four cooking zones, integrated induction controls and a flush integrated backsplash — the only rangetop in the line that is induction by definition rather than by option, which makes it the one where E2, U400 and Er are always the relevant vocabulary.
One model, no siblings
La Cornue lists exactly one appliance whose model number begins T4, so there is no nearby variant to confuse it with — and no second model to borrow a part from either, which is worth knowing before a repair is agreed.
Does this appliance publish error codes?
Yes. The codes most often seen on this kind of appliance are covered in our archive, each on a page of its own with what it means and what gets checked first: La Cornue cooktop error code E2, La Cornue cooktop error code U400, La Cornue cooktop error code Er.
Checking the number
T40USAA is a current model in the manufacturer's own catalog, which is where this page took it from. Read the number off the rating plate rather than off a receipt or a delivery note, and photograph it — these numbers are long and one wrong character sends a technician to the wrong parts list.
This article is based on:
- Official manufacturer documentation
- Internal repair procedures

Questions about La Cornue T40USAA repair
Is the T40USAA still worth repairing?
Usually. The G4 Château Series rangetops was built to be repaired, and a cabinet in good condition with sound cabinetry is worth keeping well past twenty years. Where the work approaches what the unit is worth, or a second major failure is already visible, we say so on the visit rather than after.
Can you still get parts for the T40USAA?
For most of what fails, yes — OEM parts are ordered against your model. Legacy parts can take a few days to source, which is why we confirm a part is the problem before ordering it rather than after.
Where do I find the full model number on a T40USAA?
On the data plate on the appliance itself, which is usually inside a door frame or behind a grille. Photograph the whole plate rather than writing it down — the letters after the digits decide which parts fit, and they are the part people misread most often.
What tends to go wrong on the T40USAA?
Judging by what its owners search for: induction zone not heating, induction shows e2 and shuts off, and cracked induction glass. Each of those has a page explaining the likely causes and what to check before booking anything.
Do you publish specifications for the T40USAA?
No. Capacity, dimensions, configuration and production years are not something we can verify, and a plausible-looking table of them would be invention rather than information. What we can tell you is what the number means for a repair.
