How to Fix / Troubleshooting
Safety first: Turn off and unplug the air fryer immediately. Do not continue using it until inspected.
- Visual inspection: After cooling, open the housing and inspect the heater terminals, wiring, and PCB for burn marks or melted plastic.
- Tighten connections: Ensure all screw and spade terminals on the heater and fan motor are tight.
- Replace burnt components: Any component showing signs of arcing or burning (discolored metal, charred insulation) must be replaced. Do not attempt to tape over burnt wires.
- Professional evaluation: If you cannot identify the source of the smell, have a qualified technician inspect the unit. Electrical arcing is a serious fire hazard.
