Safety first: Turn off power at the breaker before accessing any internal components.

Allow to cool: Turn the cooktop off and let it cool for at least 30 minutes. Restart and test. If F2 does not return, it may have been temporary overheating from heavy use.
Check ventilation: Verify that the cooktop has the required clearance and ventilation openings as specified in the Asko installation manual. Remove any stored items blocking airflow under the cooktop.
Inspect cooling fan: From below, remove the access panel and check that the cooling fan spins freely and is not obstructed by insulation or debris. With power restored, briefly turn on a zone and confirm the fan runs. If the fan does not run, it likely needs replacement.
Power module check: If ventilation and fan are OK but F2 recurs quickly, the affected power module may be overheating internally and require replacement.

Do not operate the cooktop with a non-functioning cooling fan; this can permanently damage the power modules.

Induction cooktop displays F2 and disables one or more cooking zones.
