E9 is displayed and the unit shuts off mid-cycle without completing cooking.

How to Fix / Troubleshooting

Safety first: Unplug the air fryer and allow it to cool completely.

Ventilation and cleaning:

Verify that the air fryer is used on a hard, heat-resistant surface with clear airflow around the rear and sides.
Clean the rear exhaust grille and any removable filters with a soft brush or vacuum to remove dust and grease.
Clean the interior cavity, heater shield, and around the thermostat/sensor with a degreasing cleaner safe for appliances.

Fan and sensor check:

Access the fan and heater assembly. Confirm the fan spins freely and runs at full speed during operation; replace the fan motor if weak or noisy.
Ensure the thermal sensor or thermostat is firmly mounted in its bracket and not hanging loose or touching the heater directly.

Test: After reassembly, run a short cycle with an empty basket to confirm that E9 does not reappear.
