A:Answer Thank you for your inquiry! The small round cover inside the freezer of your Insignia™ 18 Cu. Ft. Top-Freezer Refrigerator, located just below the air outlet, is likely part of the internal air duct system that helps regulate airflow. If it keeps falling off, the issue may be due to a loose or worn clip, a broken or missing tab, or improper alignment when reattaching it. Carefully inspect both the cover and the mounting area for any visible damage or warping. If the clips are intact but not holding firmly, you might try using a small amount of food-safe silicone or removable adhesive putty to help secure it without damaging the appliance.
