Safety first: Allow the unit to cool completely before handling. Unplug before cleaning or disassembly.

Improve ventilation: Ensure the Gourmia air fryer has at least 5 inches (12 cm) clearance on all sides and is not placed under low cabinets where heat can accumulate.
Clean interior and vents: Remove basket and tray. Clean grease from the interior, heating element area, and especially the rear exhaust vents using a damp cloth and mild detergent.
Check fan operation: During a test cycle, listen for strong airflow from the exhaust. If airflow is weak or intermittent, inspect the fan motor and blades for obstructions or failure.
Inspect high-limit thermostat: With the unit unplugged and cover removed, locate the high-limit thermostat near the heater. If it shows signs of overheating or tests open at room temperature, replace it.
Re-test: After cleaning and any part replacement, run a full cooking cycle and monitor whether the unit still shuts off prematurely.

Air fryer turns off mid-cycle and will not restart until it cools down.
