When a cooking zone is switched off the residual heat symbol appears in the display to show that the surface is still above 140 °F and can still burn. It goes out on its own as the glass cools. Along with the pan detector symbol, A for automatic heat-up, L for child lock, L1 and L2 for the low and simmer settings and P for power boost, it is one of the indicators this hob uses — and only three things on that display, E2, U400 and Er, are actually problems. ### Quoted rather than interpreted > When a cooking zone is switched off, the residual heat indicator symbol [H ] will appear in the display. This shows that the cooking zone temperature is above 140 °F (60 °C) and may still cause burns. From the CornuFé 110 induction installation and user guide (U111136-03, January 2023), in a User Guide & Service Manual downloaded from La Cornue’s own site. Nothing on this page is decoded beyond what that sentence says. ### Which machines this one applies to La Cornue induction cooktops and rangetops, and the electric and multifunction ovens. La Cornue publishes three codes in the whole of its US documentation and its Château guide carries no troubleshooting section, so a behavior missing from this archive is not proof that your appliance cannot do it — the maker simply never wrote a table for it. What its guides do document, they document in sentences, and those are on this site under the maker’s own wording. The model number, and which top the range was ordered with, settle what any of it means. ### What to do about it - Read it as information. The zone is hot, that is all it says. - Wait for it to clear rather than cleaning the glass while it shows. - Learn the rest of the indicators too — an L that a child switched on accounts for a surprising number of calls about dead cooktops across this industry. - If H shows on a zone that has not been used, or never clears, that is worth a look — a temperature sensor reading wrongly can produce it. - Do not confuse it with a code. Three codes exist on this make and H is not one of them. ### Where this goes next The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 614-3699](tel:+13056143699) and describe what the display is doing before booking anything.
