How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a tripping breaker. Unplug the air fryer before inspection.

Steps to investigate tripping:

  • Dry the unit: If the air fryer was recently cleaned or exposed to moisture, allow it to dry for 24 hours in a warm, dry area before retesting.
  • Inspect cord and plug: Look for cuts, crushed sections, or burn marks. Replace the cord if damaged.
  • Test heater to ground: With the unit unplugged and heater leads disconnected, measure resistance from each heater terminal to the metal chassis. A low resistance indicates a ground fault; replace the heater.
  • Check for visible shorts: Inspect the main PCB and wiring for burnt spots or melted insulation. Replace damaged components or wiring.

Note: Persistent breaker trips after basic checks require professional diagnosis to ensure safety.
