Possible Causes

Shorted NTC sensor reading low, Stuck heater relay on PCB, Faulty control algorithm on main board, Blocked temperature sensing path by foil or liner

How to Fix / Troubleshooting

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

  • Remove liners: Do not cover the entire basket or pan with foil or solid liners that can block airflow and temperature sensing.
  • Clean sensor area: If your model has a visible temperature probe, gently clean it with a damp cloth to remove baked-on grease.
  • Test at low temperature: Run a short cycle at a low setting and monitor. If it still overheats or smokes, stop using the unit.

Warning: Overheating due to control failure is a fire risk. Have the NTC sensor and control PCB inspected and replaced if necessary.
