Possible Causes

Blocked cooling path for electronics, Failed PCB-mounted temperature sensor, Dust buildup on control PCB, Fan not adequately cooling upper housing

How to Fix / Troubleshooting

Safety first: Disconnect from mains and allow the unit to cool. Avoid touching the heater area immediately after use.

  • Improve ventilation: Ensure the air fryer is not placed under low cabinets or against walls. Provide at least 10–15 cm clearance above and behind.
  • Clean internal dust: Open the housing and gently blow out dust from the control PCB and around the fan using compressed air. Do not spin the fan excessively with air pressure.
  • Check PCB sensor: Some Severin boards have a small NTC or thermal sensor near power components. Verify it is firmly attached and not bent away from the board. If cracked or dislodged, replace the main control PCB.
  • Verify fan airflow: Confirm that the convection fan is running at full speed during operation. A weak fan can cause heat buildup in the upper housing.

Warning: Persistent E9 errors after cleaning and ensuring ventilation may indicate a failing control board; continued use could damage the appliance.
