Strong burning smell or smoke from the air fryer during use (not just initial burn-in).

Safety: If you see flames, unplug the unit immediately and keep the basket closed to smother fire. Do not use water on grease fires.

• Stop use and cool: Unplug and allow the fryer to cool completely.
• Deep clean:
  • Remove basket and pan; soak and scrub to remove all grease.
  • Wipe interior walls and heater guard with a degreasing cleaner (appliance-safe) and a soft cloth.
  • Use a soft brush to gently clean around the heating element; do not bend the element.
• Check temperature settings: Avoid maximum temperature for very fatty foods; use recommended settings from the Tristar manual.
• Inspect thermostat (advanced):
  • If overheating persists at normal settings, test the high-limit thermostat and NTC sensor for proper operation.
  • Replace faulty components that allow excessive temperature.
• Do not reuse until resolved: Continued burning smell after cleaning indicates a control or sensor fault; seek service or replace the unit.
