Air fryer powers on but shows E6 and does not start; fan and heater remain off.

Safety first: Unplug the unit and let it cool. Moving parts and sharp metal edges are present inside.

Inspection steps:

• Check for obstructions: Remove the basket and drawer. Look up at the fan through the top grill. Use a flashlight to check for food pieces, foil, or other debris jammed in the fan blades.
• Manual rotation test: With the unit unplugged, gently spin the fan blades using a non-metallic tool (e.g., wooden stick) through the grill. The fan should rotate freely without grinding or sticking.
• Access the fan motor: Remove the top cover to expose the fan motor assembly. Inspect the motor bracket, shaft, and blades for signs of overheating or mechanical damage.
• Check wiring: Ensure the fan motor connector is firmly seated on the main board. Look for burnt or brittle wires.
• Continuity test (for experienced users): Disconnect the fan motor and measure resistance across its terminals. An open circuit indicates a failed motor.

Corrective actions:

• Remove any debris blocking the fan and verify it spins freely.
• If the motor winding is open or the motor is seized, replace the convection fan motor assembly.
• If the motor tests good but never receives voltage when the unit attempts to start, the fan driver circuit or relay on the main control board is likely faulty and the board should be replaced.
