Air fryer starts but shuts off mid-cycle; display goes dark and may come back after cooling.

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

Steps to address mid-cycle shutdown:

• 1. Improve ventilation: Ensure the Proscenic air fryer has adequate clearance on all sides and is not used under low cabinets. Remove any items blocking vents.
• 2. Clean vents and fan: Remove the basket and drawer. Clean grease from the interior and use a soft brush to clear dust from external vents. Access the fan and gently clean the blades.
• 3. Check fan speed: Start a cycle and listen for strong airflow. A weak or intermittent fan suggests a failing fan motor or power supply issue.
• 4. Inspect main PCB: Remove the cover and look for heat discoloration around the power supply components. If components are darkened or the board smells burnt, replace the main PCB.
• 5. Test again: After cleaning and any part replacement, run a test cycle and monitor whether the unit completes the program without shutting off.

Warning: Repeated overheating can damage plastic housings and pose a fire risk; do not ignore recurring shutdowns.
