How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a breaker that trips when using the air fryer. Unplug the unit before inspection.

Steps to troubleshoot breaker tripping:

  • 1. Try another outlet: Plug into a different circuit (non-GFCI if safe) to confirm the issue follows the appliance.
  • 2. Inspect power cord: Look for cuts or crushed sections. Replace the cord if any damage is found.
  • 3. Check for moisture: If the unit was recently cleaned aggressively or exposed to steam, allow it to dry for 24–48 hours in a warm, dry place.
  • 4. Test heating element: With the unit unplugged, disconnect the heater leads and measure resistance from each terminal to the metal chassis. Any continuity indicates a ground fault; replace the element.
  • 5. Inspect control board: Look for obvious shorts or burned components. Replace the board if damaged.

Warning: Ground faults are serious safety issues. If you are not experienced with electrical testing, seek professional service.
