Tefal Overheating / Temperature Regulation Failure

Air fryer overheats; exterior becomes very hot and food burns quickly even at normal settings.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Shorted NTC sensor, Sensor detached from heater housing, Stuck heater relay on PCB, Blocked internal airflow around sensor

Safety first: Unplug immediately if you smell burning plastic or see smoke.

Check ventilation: Ensure adequate clearance around the fryer and that vents are not blocked.
Test with thermometer: Use an oven thermometer to compare set vs actual temperature. If much higher, suspect control issues.
Inspect sensor (advanced): Verify the NTC sensor is firmly attached to the heater housing and not hanging loose.
Do not continue use: Overheating can cause fire. Replace the sensor or main PCB as needed; if unsure, seek professional service.
