How to Fix / Troubleshooting

Safety first: Repeated breaker trips indicate a potentially dangerous fault. Unplug the unit and do not continue resetting the breaker.

  • Step 1 – Try another circuit: Plug the air fryer into a different circuit (not GFCI if possible) to confirm the issue follows the appliance.
  • Step 2 – Inspect cord and plug: Look for cuts, nicks, or burn marks. Replace the cord if damaged.
  • Step 3 – Check for moisture: If the unit was recently cleaned or exposed to steam, allow it to dry for 24–48 hours in a warm, dry place.
  • Step 4 – Internal inspection (advanced): Open the housing and inspect for signs of arcing, burnt insulation, or water ingress near the heater and control board.
  • Step 5 – Professional repair: Ground faults and shorts should be diagnosed and repaired by a qualified technician. Do not attempt to bypass safety devices.
