If your **fryer overheated**, unplug it and let it cool fully — the **thermal safety cut-out** has likely tripped. Clean grease from the basket and vents, ensure good airflow, and don’t overfill it.
If it overheats again, the **thermostat or thermal fuse may be faulty** and the unit may need repair or replacement. Safety guidance is in the manual here:
