The hot pan transfers heat back to the surface. Induction technology does not make the glass immediately touch-safe after cooking.
What the observation means
The amount of stored heat depends on cookware, duration and contents. Residual-heat indicators should be interpreted through the manual and may not function during a power loss.
A useful next step
Keep hands and heat-sensitive items clear until safely cooled. Do not place a cloth or plastic container on the former cooking area because the zone is Off. Report an indicator fault separately without testing surface temperature by touch.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
