How to Fix / Troubleshooting
Safety: Turn off and unplug the air fryer immediately. Do not continue using it until the source is identified.

- Open housing: Remove covers to inspect wiring around the heater and control PCB.
- Check connectors: Look for discolored, charred, or melted spade connectors on the heater and mains input. Replace any damaged connectors and trim back burnt wire, re-terminating with high-temperature connectors.
- Inspect wiring harness: Replace any wires with melted insulation using the correct gauge and temperature rating.
- PCB inspection: Examine the control PCB for burnt components or darkened areas. Replace the PCB if any damage is found.
