AEG air fryer shows E7 and will not start; basket is fully inserted but unit reports a door/basket error.

Safety first: Unplug the appliance before inspecting internal switches or sensors.

Steps to resolve E7:

• Check basket insertion: Remove and firmly reinsert the basket/drawer until it clicks. Ensure no food debris is blocking the latch or rails.
• Inspect latch and tabs: Examine the basket front and side tabs that engage the internal switch. If a plastic tab is broken or worn, the basket may not actuate the switch; replace the basket/drawer assembly if necessary.
• Access the switch/sensor: Remove the front or side panel to locate the basket detection microswitch or magnetic sensor. Verify that it is securely mounted and aligned with the basket tab or magnet.
• Test the switch: With a multimeter in continuity mode, actuate the switch manually. It should open and close reliably. Replace the basket detection microswitch if intermittent or non-functional.
• Check wiring: Inspect the harness from the switch to the main PCB for pinched or broken wires. Repair or replace as needed.
• Reassemble and test: Refit panels, insert the basket, and start a short cycle to confirm that E7 is cleared.
