Display shows E6 and the unit will not start or shuts off shortly after starting; sometimes accompanied by fan not running.

Safety first: Unplug the air fryer and allow it to cool. Do not insert fingers or tools into the fan area while the unit is plugged in.

Step-by-step checks:

• Listen for fan operation: When you start a cook cycle (before unplugging), note whether you hear the fan spin up. If it is silent or makes grinding noises, suspect the fan motor or obstruction.
• Inspect fan from rear or top: Remove the rear or top cover to access the convection fan assembly. Check for food debris, foil, or warped plastic contacting the blades.
• Spin test: With the unit unplugged, gently spin the fan by hand. It should rotate freely without scraping. If it is stiff or seized, the motor bearings may have failed.
• Check wiring: Inspect the fan motor connector and wires leading to the main control board. Reseat any loose connectors and look for burnt or pinched wires.
• Voltage test (advanced): With extreme caution and only if experienced, you can test for voltage at the fan motor terminals when the unit is running. If proper voltage is present but the fan does not run, the motor is defective. If no voltage, the control board or relay is at fault.

When to stop: If the fan motor is noisy, seized, or does not run with proper voltage, replace the fan motor assembly. If you are not comfortable working around live voltage, seek professional service.
