Display shows E6; fan may run but there is no heat, or unit shuts down shortly after starting.

Safety first: Unplug the unit and wait until all internal parts are cool before opening the housing.

Steps to resolve E6:

• Check for obstructions: Remove the basket and drawer. Look up toward the fan behind the heating element. Ensure no food pieces, parchment paper, or foil are stuck in the fan blades.
• Spin test: With the unit unplugged, gently spin the fan blades with your finger or a non-metal tool. They should rotate freely without scraping. If stiff or jammed, the convection fan motor may be failing or obstructed.
• Access the fan motor: Remove the top or rear cover to reach the fan motor assembly. Inspect the blades for grease buildup and clean carefully.
• Check wiring: Verify that the fan motor connector is fully seated on the main control PCB and that wires are not pinched or heat-damaged.
• Motor test: For experienced DIYers, measure resistance across the fan motor terminals. An open circuit indicates a failed motor. Some SilverCrest models use a motor with built-in tachometer feedback; if the motor runs but E6 persists, the feedback circuit may be faulty.
• Replace the motor: If the motor is noisy, seized, or electrically open, replace the complete convection fan motor assembly.

Warning: Do not run the air fryer with the fan removed or disabled; this will cause rapid overheating and potential fire.
