Hot-Surface Indicator Stays On Cold
The hot-surface light on a Wolf cooktop warns that the glass is still hot, and it can stay lit well after every zone is off, because glass gives up its heat slowly.
| If you see | And | Then | Verdict |
|---|---|---|---|
| Hot light still on after you switch off | Something was cooked on the top a short while ago | Normal. A hot pan warms the glass beneath it, and the light waits for that heat to fade. | Safe to wait |
| Light lit, and you want to wipe the top | The light has not gone out yet | Wait for it. Wolf's older CT guide counts the top safe to clean only once that light is dark. | Safe to wait |
| No light at all straight after hard cooking | A zone was on high a minute ago | The warning is not showing. Treat the glass as hot regardless, keep hands clear and book a check. | Call today |
| Light still lit the next morning | Nothing has been cooked since last night | The glass will have cooled overnight, so the light or whatever reads the heat is at fault. Leave the top unused. | Call today |
If the hot-surface light stays on long after the glass has had every chance to cool, call Redmond Wolf Repair, (425) 905-2822, and leave the top unused meanwhile.
What the light is reading
On the older CT induction models Wolf spells it out: the light comes on once the surface over any zone passes 150°F (65°C), the display shows HOT, and both stay until the whole surface has cooled to a safe level, with the controls on or off. The current guide for the CI induction and CE electric tops says only that the light may remain lit after the cooktop is off, and gives no time for it.
Why induction glass gets hot at all
An induction zone puts its heat into the pan, not the glass, and Wolf notes that the surrounding surface stays relatively cool. The glass directly under a pan is another matter: it sits against hot metal and takes on its heat, which is why Wolf warns against touching the glass over or beside a zone in use. On a radiant electric top the element heats the glass itself, so the glass holds heat for longer there. Do not test it with your hand; the light is there so that you need not.
