# La Cornue teppanyaki element repair

### About the teppanyaki module

An electric griddle: a solid plate held anywhere between 140 and 482 °F by a 2,000 W element, a sensor and a control. Nothing in it is consumable and nothing is adjustable, so the diagnosis is a meter — resistance cold, current under load, sensor output against actual plate temperature at several points rather than one. A bowed plate is checked for separately, because a plate that is no longer flat cooks unevenly whatever the control does. It is also the module most likely to be discovered broken rather than to break in front of anybody, because it gets used a few times a year.

What this involves

Element, sensor and control measured separately

The plate checked for flatness — a bowed griddle cooks unevenly and is not a control problem

Temperature verified across the surface, not at one point

Measure the element

Resistance cold, current under load. An open element is unambiguous and everything else is not.

Test the sensor and the control

A plate that reaches one temperature and ignores the dial is usually the sensor, not the element.

Check the plate for flatness

A bowed griddle cooks unevenly and no control repair will change that.

Verify across the surface

Several points, not one. The specification is 140 to 482 °F and the whole plate is meant to hold it.

Reassemble and re-test hot

Electric problems that appear only at temperature are missed by a cold test.

### It smokes and food sticks. Repair or technique?

Often technique, and we would rather say so. A griddle needs the right temperature for what is on it and it needs to be genuinely clean — carbonised residue sticks and smokes at temperatures a clean plate handles happily. Check the reading against the dial though: a sensor that has drifted high will smoke at a setting that used to be right, and that is a repair.

### Is there a substitute part?

No, and we will not fit one. A plate element for this module is specific to the make; there is nothing generic that belongs in it. Where a part has a lead time we quote the wait before ordering rather than discovering it afterwards.
