Air fryer powers on but will not start cooking; pressing start does nothing and no error code is shown.

Safety first: Unplug the unit before any internal inspection.

User-level steps:

• Confirm settings: Ensure a cooking mode, temperature, and time are selected before pressing start.
• Basket insertion: Remove and firmly reinsert the basket until it is fully seated.
• Panel reset: Unplug for 5 minutes, then plug back in and try again.

Further checks:

• If other buttons respond but the start button does not, the touch panel may be faulty.
• If the unit beeps when the basket is removed/inserted, the safety switch is likely working; if not, inspect the basket safety microswitch and its wiring.

Replace the touch control panel if the start button area is unresponsive. Replace or adjust the basket safety microswitch if the unit does not detect basket insertion.
