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 T43
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.
-
No flame, and no obvious reason Burner will not light
One burner dead while the others work is a different problem from a whole top that will not light, and the two are worth separating before anybody calls anybody. On brass burners in a humid kitchen the single dead burner is nearly always the electrode or the ports; a whole top points at the ignition module or the gas supply.
- One burner out is that burner — not the module
- All of them out is ignition or supply, and it is quick to tell
- Never hold the knob in while it clicks
-
The spark is there and the flame is not Burner clicks but will not ignite
Continuous clicking with no flame — or clicking that carries on after a burner has lit — is one of the two or three most common calls on any gas range, and on this one it has a short list of causes. It is also the symptom people live with longest, and it should not be: every click is unlit gas.
- Clicking after ignition is usually a wet or dirty electrode
- Clicking on every burner at once points at the module
- It is a small part and a same-visit job in most cases
-
It lights, but there is no heat in it Weak or uneven flame
A burner that lights cleanly and produces half the heat it used to, or a flame that is tall on one side of the crown and absent on the other. On a range whose front burners are rated at 17,000 BTU and whose power burner is rated at 22,000, a weak flame is not a small loss — it changes what the range can do.
- Uneven around the crown is ports or a misseated cap
- Weak on every burner is supply pressure or a regulator
- The plaque burner is the one nobody notices has weakened
-
The plaque has cold areas French top heats unevenly
The plaque coup de feu is meant to be uneven — hottest directly above its single burner and cooler as you work outwards, which is the whole point of cooking on one. What is not meant to happen is a cold center, a dead quarter, or a plate that no longer reaches the temperature it used to.
- Graded heat is the design — a cold center is not
- Most plate complaints start with the burner underneath
- Rust and scale on the underside change conduction

About La Cornue T43 repair
What this model is
Châtelet Rangetop 135 — a a 53.15-inch Château rangetop, 1350 mm wide and 200 mm deep in the counter. 1350 mm wide, 53.15 inches, 200 mm high — a rangetop rather than a range, so it drops into a counter with no ovens beneath it. About 220 lb uncrated and 320 lb crated, and a choice of seven top configurations. The modules are the same as the range's: gas burners, the plaque coup de feu, the lava-rock grill, induction and teppanyaki, mixed to the order. So the repair is the module's repair, and the configuration code says which modules are there.
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?
A purely gas rangetop publishes no codes at all.
Checking the number
T43 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.

Questions about La Cornue T43 repair
Is the T43 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 T43?
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 T43?
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 T43?
Judging by what its owners search for: burner will not light, burner clicks but will not ignite, weak or uneven flame, and french top heats unevenly. Each of those has a page explaining the likely causes and what to check before booking anything.
Do you publish specifications for the T43?
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.
