Induction zone stops heating and F2 appears on the display

Safety first: Turn off all cooking zones and disconnect power at the breaker. Allow the cooktop to cool completely before inspection.

User actions:

• Remove large pots or griddles that cover multiple zones and control area.
• Check that air can circulate under the cooktop: remove any stored items from the cabinet directly beneath the unit.
• After at least 20–30 minutes of cooling, restore power and test at a moderate power level.

Technician actions:

• Access the underside of the cooktop and locate the cooling fan assembly.
• Visually inspect the fan for grease buildup, obstructions, or broken blades. Clean carefully with a soft brush and vacuum.
• Power the fan (following Liebherr service instructions) and verify it runs smoothly. Replace the cooling fan motor if seized or noisy.
• Check ventilation channels and baffles for dust or insulation blocking airflow.
• Test the temperature sensor on the power module (if separate from glass NTC) for correct resistance. Replace if out of spec.
• If all thermal components are good, the induction power module may be misreading temperature and should be replaced.
