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

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

Steps to address mid-cycle shutdown:

• 1. Improve ventilation: Ensure at least 5 inches (12 cm) clearance around the air fryer. Do not operate in a cabinet or against a wall.
• 2. Deep clean interior: Remove basket and drawer. Clean the interior walls, bottom pan, and especially the area around the heating element and fan guard with a degreasing cleaner on a cloth. Do not soak the unit.
• 3. Check fan operation: During a test run (before it overheats), listen for strong airflow. Weak or intermittent fan noise suggests a failing convection fan motor.
• 4. Access high-limit thermostat: With the unit unplugged and cool, remove the rear or bottom cover. Locate the high-limit thermostat mounted on or near the heater housing. Some are resettable; press the reset button if present.
• 5. Replace weak thermostat: If the thermostat trips at normal temperatures or shows signs of heat damage, replace it with an OEM-rated high-limit thermostat.

Do not bypass thermal safety devices; they prevent fire and severe damage.
