Error codeH
ApplianceInduction Cooktop
What H tells you
H is not a fault. After a zone is switched off it keeps heat for a while, and the display shows H as long as the glass over that zone is above 140 °F (60 °C). Below that temperature the symbol goes out on its own.
The heat comes from the pan: an induction zone warms the base of the cookware, and the glass under it picks up that heat.
While H is showing
Do not touch the zone; it can still burn.
Do not set anything that is sensitive to heat on the glass over that zone.
Where the manuals list it
Château G4 induction hob module
Albertine 36 and CornuFé 44 induction ranges
The older La Cornue knob-controlled induction hob (2010 instructions)
The installer check list for the CornuFé 36 and 44 inch induction ranges also notes that H appears during the zone test once the glass gets hot.

L is the other status letter: the controls are locked.
