Possible Causes

Failed temperature sensor on zone, Faulty indicator circuit on control board, Shorted indicator LED

Safety first: Always treat a zone with a lit residual heat indicator as hot until proven otherwise.

Allow full cool-down: Leave the hob unused for several hours and check if the indicator goes out.
Power reset: Turn off at the mains for a few minutes to reset the control electronics.
If indicator remains on: The sensor or control circuit is likely faulty. While this is usually safe, it can mask a real overheat condition; arrange service.
Technician repair: Replace the affected sensor or control PCB as per Montpellier service instructions.
