E7 error appears and the fan does not run, or the unit shuts down shortly after starting.

Safety first: Unplug the air fryer and let it cool fully before inspection.

• Check for fan operation: Start a cycle and listen closely (with the basket in place). If the fan does not start or makes a grinding noise before E7 appears, suspect a fan issue.
• Inspect for obstructions: Remove the basket and look up at the fan through the grill. Check for food pieces, foil, or warped plastic touching the blades. Remove any debris with long‑nose pliers or a plastic tool.
• Access the fan motor: Remove the outer shell and top cover to expose the fan motor assembly. Spin the fan by hand; it should rotate freely. If stiff or seized, replace the fan motor assembly.
• Check wiring and connector: Ensure the fan motor plug is fully seated on the main PCB and that the wires are not damaged or pinched.
• Test motor (advanced): If you are competent with electrics, you can briefly power the fan motor with an appropriate low‑voltage supply (for DC motors) or mains (for AC motors, with extreme caution) off the board to confirm operation. If the motor runs off‑board but not in the fryer, the PCB driver is likely faulty.
• Replace faulty parts: Replace the fan motor assembly if it does not run freely or fails under power. If the motor is good but E7 persists, replace the main control PCB.
