How to Fix / Troubleshooting
Safety first: Immediately unplug the air fryer and do not continue using it until inspected. Fire risk is possible.
- Step 1 – Visual inspection: After cooling, remove the housing and inspect wiring around the heating element, fan motor, and control board for melted insulation or burn marks.
- Step 2 – Check connectors: Tighten or replace any discolored or loose spade connectors. Replace any burned wires with high-temperature appliance wire.
- Step 3 – Component check: Look for charred components on the control board or motor. Replace the affected part (e.g., convection fan motor or main control board).
- Step 4 – Do not ignore: If you cannot locate the source, have a professional technician inspect the unit. Do not resume use until the cause is resolved.
