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

Safety first: Disconnect from mains before mechanical adjustments.

• Check basket position: Remove and firmly reinsert the basket until it is flush with the front and you feel it latch.
• Inspect rails and guides: Look for bent metal or plastic guides that prevent full insertion. Straighten gently or replace the drawer if warped.
• Test safety switch: Access the basket detection switch and test continuity when the drawer is fully inserted. Replace the switch if it does not change state.
• Control reset: After mechanical checks, unplug for 5–10 minutes, then reconnect and attempt to start a simple manual cook program.
• Board replacement: If the switch is working but the unit still refuses to start, the main PCB may not be reading the input and should be replaced.

Warning: Never defeat the safety switch to run the unit with the basket removed.
