How to Fix / Troubleshooting
Safety first: Immediately turn off and unplug the air fryer if you smell burning plastic or electrical odor. Do not continue using until inspected.
Steps to investigate:
- 1. Check inside cavity: After cooling, remove the basket and inspect for any plastic utensils, packaging, or liners that may have melted. Remove and clean thoroughly.
- 2. Inspect wiring: Remove the housing and carefully inspect all wiring near the heating element and fan. Look for melted insulation, darkened connectors, or scorch marks.
- 3. Tighten connections: Secure any loose spade connectors on the heating element and power input. Replace any discolored or burned connectors.
- 4. Replace damaged parts: Replace any burned wires with high-temperature appliance wire and replace the heating element assembly or main control PCB if they show signs of overheating.
- 5. Test cautiously: Reassemble and run a short test cycle while monitoring for odor. If smell persists, discontinue use and consult a technician.
