La Cornue offers an electric teppanyaki as one of the cooktop module options on the Château range — a flat, solid griddle plate used for direct, high-heat cooking of items like steak, seafood, and vegetables, sitting alongside gas burners, a French top, or a lava-rock grill depending on how the cooktop was configured. Because it is electric rather than gas, a teppanyaki that will not heat is a different kind of problem from a burner that will not light, even though they sit inches apart on the same range.
Electric, Not Gas — Why That Matters
There is no igniter, no orifice, and no flame to check on a teppanyaki plate. Heat comes from an element underneath the plate, controlled by its own switch or dial, wired into the range’s electrical side rather than its gas manifold. A plate that will not heat at all is either not getting power, or the element itself has failed — there is no middle step involving gas pressure or a spark to rule out first.
Start With the Obvious
Before assuming the element has failed, confirm the control for the teppanyaki is actually turned on and seated correctly, and check whether other electric functions on the range — an oven light, a display, an induction zone if fitted — are working normally. A range-wide power problem looks identical to a single failed element from the plate’s side, but they are very different repairs.
Unequal Heat Across the Plate
A teppanyaki that heats, but unevenly across its surface, with one area noticeably hotter than another, points at the element itself rather than the power supply — an element does not go from working to not working evenly across its length, it tends to degrade unevenly first. This is worth mentioning specifically when booking a visit, since “heats unevenly” and “does not heat at all” are checked differently.
What Not to Do
The element and its wiring sit inside a sealed enclosure underneath the plate, not a place meant to be opened during normal use. Continuing to run a teppanyaki that heats unevenly, on the assumption it will sort itself out, risks the element failing completely rather than being replaced while it is still partly working — and opening that enclosure yourself is a technician’s job, not a weekend project.
Cleaning Between Uses
Because the plate is solid and flat rather than a set of burner rings, residue and grease sit directly on the cooking surface and, if left, can affect how evenly heat reads across it once it is turned on again. Cleaning the plate once it has cooled, the same way any flat cooking surface is cleaned, is worth doing before assuming an uneven heat problem is electrical rather than simply a dirty surface.
If your teppanyaki will not heat, or heats unevenly, a La Cornue cooktop repair visit checks the power supply and the element before recommending a part.
