A smoking air fryer is almost always fixable and rarely a fault. Nine times out of ten it's fat hitting the heating element. Here are the four usual causes and the quick fix for each.
Key takeaways
Q: Why is my air fryer smoking?
A: Usually fat dripping onto the hot element from fatty foods. Add a tablespoon of water to the drawer beneath the basket to stop it.
Q: Is a smoking air fryer dangerous?
A: It's usually just burning grease, not a fault — but switch off, let it cool and clean it before carrying on.
The four causes
| Cause | Sign |
|---|---|
| Fat hitting the element | Cooking fatty food (bacon, sausages, mince) |
| Grease build-up | Smoke even with low-fat food |
| Loose, light food | Bits flying up near the element |
| Temperature too high | Burning oil or seasoning |
Quick fixes
- Add water to the drawer. A tablespoon beneath the basket stops fat smoking.
- Clean after fatty cooks. Old grease is a common hidden cause.
- Secure light foods or use a liner so nothing flies into the element.
- Lower the temperature if oil or seasoning is scorching.
