Can an air fryer set off a smoke alarm normally?

Yes, it is normal for an air fryer setting off smoke alarm, particularly when using high temperatures or frying particular foods.

Hot air is circulated in air fryers to cook food, and this process can produce smoke whilst cooking foods with a number of fats or the use of quite a few oils.

When oil and fat splash, food bits trapped in the heating part, or stuff building up inside the air cooker can all lead to smoke. 

Also, if the smoke detector is put too near to the kitchen or it’s made extra good at picking up small signs of smoke, there may be more chances for it to spot something wrong and start making noise.
