Air fryer shows E8 and shuts down unexpectedly during cooking.

Safety: Unplug the unit before any disassembly. Mains voltage is dangerous.

• Check external power:
  • Plug the air fryer directly into a wall outlet (no extension cords or power strips).
  • Test a different outlet known to be good.
• Inspect power cord:
  • Check the Tristar power cord for cuts, kinks, or burn marks.
  • Gently wiggle the cord at the plug and at the entry to the fryer; if the unit powers off or flickers, the cord or inlet may be faulty.
• Check power inlet (advanced):
  • Remove the rear cover to access the power inlet socket and wiring.
  • Ensure all spade connectors are tight and not discolored.
• Control board inspection:
  • Visually inspect the main control PCB for burnt components in the power supply section (near where the mains wires connect).
  • Bulged capacitors or burnt resistors indicate board failure.
• Replace components: Replace a damaged power cord or inlet socket. If the internal power supply on the PCB is faulty, the entire main control board should be replaced.
