Air fryer powers on but will not start when Start button is pressed.

Safety first: Unplug the unit before accessing internal switches or boards.

• Verify basket position: Remove and firmly reinsert the basket until it clicks. Some Kenmore models will not start unless the basket is fully seated.
• Check for error icons: Look for a door/basket icon on the display indicating the safety switch is open. If present, focus on the basket switch.
• Test Start button: Try pressing other buttons. If only the Start button is unresponsive, the touch panel may be faulty.
• Inspect basket switch: Access the basket microswitch and test continuity while inserting the basket. Replace the switch if it does not change state.
• Control board: If the switch and touch panel test good but the unit still will not start, the main control board input circuit may be defective and should be replaced.
