How to Fix / Troubleshooting

Safety first: Unplug and allow the unit to cool before inspection.

Steps:

  • Ventilation: Ensure at least 10 cm clearance around the air fryer and that vents are not blocked.
  • Clean vents: Use a soft brush or vacuum to clear dust and grease from intake and exhaust vents.
  • Check power cord seating: Confirm the cord is firmly plugged into the outlet and not loose at the entry point of the appliance.
  • Internal inspection (experienced users): Open the housing and inspect the main board for signs of overheating (discolored PCB, bulging capacitors). Check the thermal fuse and thermostat for signs of heat damage.

If the unit consistently shuts down at similar times in the cycle, replace the overheat thermostat or thermal fuse as appropriate. If the board shows heat damage, replace the main control board.
