Air fryer shuts off mid‑cycle; display goes dark and then may come back after cooling.

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

• Ventilation check: Ensure at least 10 cm clearance around the fryer. Remove any objects blocking the rear or side vents.
• Clean vents and fan intake: Use a soft brush and vacuum to remove dust and grease from intake and exhaust grills.
• Fan performance: Listen during operation to ensure the fan maintains a steady speed. If it slows or stops before shutdown, the fan motor may be overheating and should be replaced.
• Inspect thermal devices: Access the heater assembly and locate the thermal fuse and thermostat. Check for signs of heat damage. Replace any device that opens at too low a temperature (requires testing by a technician).

Repeated thermal shutdowns indicate a serious airflow or component issue; do not continue using the fryer until resolved.
