E10 appears and the air fryer will not start; sometimes accompanied by a beeping alarm.

Safety first: Unplug the air fryer before inspecting the switch or internal wiring.

Steps to address E10:

• 1. Check basket insertion: Remove the basket and drawer, then firmly reinsert them until you hear or feel a click. Many Granitestone models require the drawer to fully engage a basket safety switch.
• 2. Inspect the drawer rails and latch: Look for bent metal, plastic burrs, or food debris preventing full closure. Clean the rails and latch area thoroughly.
• 3. Locate the door/basket switch: With the housing removed, find the door/basket microswitch near the front where the drawer slides in. Manually press the switch lever and listen for a distinct click.
• 4. Test the switch: If you have a multimeter, test the switch for continuity when pressed. Replace it if it does not open and close properly.
• 5. Check actuator tab: Ensure the plastic or metal tab on the drawer that presses the switch is intact and not broken. If damaged, the basket/drawer assembly may need replacement.
• 6. Replace faulty parts: Install a new door/basket microswitch or drawer assembly as needed. Reassemble and test for proper operation.
