What H Means
La Cornue’s manual documents [H] as the residual heat indicator: the cooking zone is still hot from the pan that was heating on it, even though the zone itself has been switched off. It disappears once the manual’s stated 60°C threshold is reached.
Common Causes of H
- Normal residual heat left in the ceramic glass and cookware after a cooking zone that was recently in use is switched off
🔧 One Safe Check You Can Try
No action is needed beyond leaving the zone alone until [H] clears on its own. The manual specifically warns not to touch the cooking zone or place anything heat-sensitive on the ceramic glass while [H] is showing, citing a risk of burns and fire.
⚠ Why You Shouldn't Go Further Than That
- The manual’s own instruction is to wait for [H] to clear rather than to intervene while it is showing, since the surface is still hot enough to burn.
