E7 error appears and the unit will not start; sometimes accompanied by beeping.

Safety: Unplug the air fryer before inspecting the switch area.

• Check basket insertion:
  • Remove the basket and pan, then reinsert firmly until you hear or feel a click.
  • Ensure no warped accessories or liners are preventing full insertion.
• Inspect switch actuator:
  • Look at the area where the basket slides in; locate the small plastic tab or lever that presses the internal microswitch.
  • If the tab is broken or bent, the switch will not engage and the housing or basket guide may need replacement.
• Access the switch (advanced):
  • Remove side or bottom screws to open the housing near the basket slot.
  • Locate the microswitch and check that its lever moves freely.
  • Verify that the wiring connector is firmly attached.
• Test the switch:
  • With a multimeter, test continuity across the switch terminals while pressing the lever.
  • No change in continuity indicates a failed switch.
• Replace parts: Replace the door/basket microswitch if defective. If the switch is good but E7 remains, inspect the main control PCB input circuit.
