Air fryer maintenance: Common habits that damage appliances

To ensure the longevity and safety of air fryers, users should avoid several common operational mistakes. One major error is placing the device in cramped spaces or blocking air vents. Brands such as Ninja and Instant warn that obstructing ventilation can cause overheating and internal damage due to sudden temperature spikes.

Another critical issue is failing to clean grease and food residue from the heating element. Philips advises thorough cleaning of both the interior and the heating surface, as accumulated residue can cause smoke, odors, and reduced heat efficiency, potentially leading to burnt food. Additionally, users should avoid using steel wool or metal tools for cleaning to prevent damage to the appliance.
