How to Fix / Troubleshooting

Safety: Unplug the unit before accessing control components. Some warmth around the door can be normal, but excessive heat is not.

Steps to investigate:

  • Check installation: Ensure adequate ventilation space around the unit as per SMEG guidelines.
  • Monitor operation: After reconnecting power, feel the door frame periodically. If it remains very hot, the door heater may be stuck on.
  • Control PCB check: The door heater is usually controlled by the main PCB. If it does not cycle off, the PCB may be faulty and require replacement.
  • Professional service: Door heater circuits are not typically user-serviceable; contact a technician for diagnosis and repair.

Note: Excessive door heat can also increase internal temperature and energy consumption.
