How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a breaker that trips. Unplug the air fryer immediately. Risk of fire or shock exists.

Steps to investigate:

  • 1. Try a different outlet: Use another properly grounded outlet on a different circuit to confirm the issue follows the appliance.
  • 2. Inspect power cord: Look for cuts or crushed areas. Replace the power cord if damaged.
  • 3. Check for moisture: If the unit was recently cleaned or exposed to steam, allow it to dry for 24–48 hours before retesting.
  • 4. Internal inspection: With housing removed, inspect the heating element, wiring, and control PCB for burn marks or melted insulation. Replace any shorted components.
  • 5. Professional service: If you cannot identify the fault, have a qualified technician test insulation resistance and repair as needed.
