Possible Causes
Grease on heating element burning off, Melted wire insulation near heater, Failing fan motor windings, New-unit protective coating curing
How to Fix / Troubleshooting
Safety first: If the smell is intense or accompanied by smoke, unplug immediately.
- New unit break-in: For a new Tefal air fryer, run it empty at 200°C for 10–20 minutes with good ventilation. A mild smell is normal initially.
- Inspect for grease buildup: Clean the basket, pan, and interior surfaces to remove old grease that can burn.
- Internal inspection (advanced):
- Check wiring near the heater and fan for discoloration or melted insulation.
- Inspect the PCB for burnt components.
- Do not ignore: Persistent strong burning or electrical smell indicates a failing component that should be replaced before further use.
