Possible Causes

Weak household circuit, Undersized extension cord, Failing SMPS on main PCB, Loose mains connections, Partially shorted heater drawing excess current

How to Fix / Troubleshooting

Safety first: Avoid using damaged cords or overloaded outlets.

  • Direct connection: Plug the air fryer directly into a wall outlet without extension cords or multi-way adapters.
  • Circuit load: Ensure no other high-power appliances share the same circuit.
  • Inspect connections: Check internal mains terminals and the line filter module for tightness and signs of overheating.
  • Heater current: If possible, measure current draw; significantly higher than rated wattage suggests a failing heater or short. Replace the heating element assembly if necessary.
  • Board replacement: If the SMPS cannot handle normal inrush and causes resets, replace the main control board.
