La Cornue 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.

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 code and the history
E2 during long cooking, E2 from cold and E2 after a pan boiled dry are three different conversations.
-
02
Look at the installation
What is packed into the cabinet under the hob, and whether air can reach the electronics. This is the maker's first suggestion and it is often the answer.
-
03
Test every zone properly
With a pan that meets the minimum base diameter for that zone — 4¾ inches front left, 5½ at the rear, 8¼ in the center. A small pan will not couple, and that is not a problem.
-
04
Measure supply and connection
A latched U400 is a wiring problem, and it is usually upstream of the appliance.
-
05
Then the unit
Coil, sensor and generator board, measured. An Er number goes straight here, and we say so rather than resetting it and leaving.

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

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

About La Cornue induction hob repair
About the only part of this make that reports anything
All three of La Cornue's documented codes 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 — the pan-missing symbol, H for residual heat, A, L, L1, L2 and P — and knowing which is which saves a visit. E2 is investigated as ventilation first because that is the maker's own first suggestion, every zone is tested with a pan meeting its minimum base diameter, and only then are coil, sensor and generator measured.

Before you book
Questions about La Cornue induction hob repair
Can you not just reset it?
On E2 we can and we will not leave it there. E2 is a protection: the electronics reached their limit and shut down to survive, and an appliance that trips it repeatedly is being cooked by its own environment. If the cause is the air path we say what it is and what it should be; if the installation is genuinely correct and it still trips, that is a part.
Is a dead zone always the coil?
No — it can be the coil, its temperature sensor, or one channel of the generator, and all three look identical from above. It can also be the pan: a base below the minimum diameter for that zone will not couple at all, which is why the visit starts with a proper pan and a tape measure.
