Display shows E8 and the control panel is unresponsive or the unit shuts off.

Safety: Unplug the air fryer before inspecting the cord or opening the housing. Mains voltage is present inside the unit.

Steps to troubleshoot E8:

• Check outlet and cord: Plug another appliance into the same outlet to confirm proper voltage. Inspect the Farberware power cord for cuts, kinks, or burn marks. Replace the cord if damaged.
• Inspect plug and strain relief: Ensure the cord is firmly seated in the unit (if detachable) and that the strain relief is intact.
• Access the control board: Remove the bottom cover to expose the main control PCB. Locate the AC input terminals and any onboard fuse.
• Check internal fuse: If present, test the fuse with a multimeter for continuity. Replace only with the same type and rating if blown.
• Inspect power supply components: Look for bulging capacitors, burned resistors, or cracked solder joints in the power supply section of the board. Any visible damage usually requires replacing the entire control PCB.
• Reseat connectors: Reseat all low-voltage connectors from the power supply to the display and keypad board.

Note: Component-level repair of the power supply is not recommended for non-professionals due to shock risk; replacing the complete control board is safer.
