Air fryers have become one of the most popular kitchen appliances in recent years, praised for their convenience and ability to make food crispy with less oil. However, as their use has grown, so have reports of common mistakes that many people unknowingly make when using them. One of the most widespread issues comes down to improper placement, overloading, and lack of routine cleaning—problems that can turn a helpful appliance into a potential kitchen hazard.

One major mistake people often make is placing an air fryer too close to walls, cabinets, or other appliances. Air fryers release heat through vents, usually located at the back or sides. When these vents are blocked or airflow is restricted, heat can build up quickly. Over time, this can damage the appliance, affect performance, and in rare cases lead to overheating. Manufacturers generally recommend placing air fryers on a clear, heat-resistant surface with several inches of space on all sides.
