Air fryer fan continues to run for an unusually long time after cooking has finished.

Safety first: This symptom is usually not dangerous but indicates poor cooling efficiency.

Steps:

• 1. Improve ventilation: Ensure the unit has ample space around it and is not under low cabinets trapping heat.
• 2. Clean interior: Remove grease from the heater area and sensor to improve accurate temperature sensing.
• 3. Sensor check: Verify the NTC sensor is properly attached and not insulated by grease or debris.
• 4. Control board: If the fan runs indefinitely even when cool, the control board's fan control circuit may be stuck; replacement may be needed.
