Inspect and Clean the Interior
Check for grease, food debris, or oil splatters inside the basket and on heating elements. Remove the basket and tray, then wash them with warm, soapy water. Use a soft brush or cloth to clean the heating element if accessible, ensuring no residue remains.
Remove and Clean Accessories
If you’re using liners or racks, ensure they are placed correctly and not obstructing airflow. Clean any accessories thoroughly, especially if grease or food particles are trapped.
Check for Grease Buildup or Damage
Inspect the heating element and interior surfaces for excessive grease or food residue. If buildup is heavy, perform a vinegar or baking soda cleaning cycle, or follow the manufacturer’s cleaning instructions. Replace damaged or worn accessories if needed.
