Putting an aluminum liner on the bottom of an oven can lead to several issues. Firstly, it can interfere with the oven's airflow, which is essential for proper cooking and can cause uneven heating or increase cooking times. Secondly, aluminum foil can melt and permanently damage the oven surface at high temperatures. Manufacturers often advise against this because it poses a fire hazard and could nullify your warranty. For oven protection, consider using oven mats or placing foil on the rack below the item being baked, not at the oven's bottom.
