Possible Causes

Blocked cooling vents under cooktop, Failed cooling fan for induction module, Overheated power IGBTs on module, Incorrect installation with insufficient airflow

How to Fix / Troubleshooting

Safety first: Switch off power at the isolator. Induction modules contain high-voltage components.

  • Allow to cool: Let the cooktop cool for at least 30 minutes. Ensure no pans are left on active zones.
  • Check ventilation: Inspect the cabinet beneath the cooktop. Ensure Falcon’s specified clearance and ventilation openings are present and not blocked by drawers or stored items.
  • Fan operation: Restore power and run a low-power setting. Listen for the internal cooling fan. If the fan does not run, disconnect power and replace the fan.
  • Module inspection (technician): Remove the cooktop and access the induction power module. Look for burnt components or discoloured PCB. Replace the module if damaged.

Persistent F21 errors after ensuring proper ventilation indicate a failing power module that should be replaced by a qualified technician.
