How do you Ensure Proper Air Circulation?
In order to ensure proper temperature, you need to permit proper airflow in the freezer. Cool air enters through the freezer wall and moves downward. The air then recirculates through the vent near the bottom.
Do not block any of these vents with food packages. If the vents are blocked, airflow will be obstructed, which can result in temperature and moisture problems.
IMPORTANT: To avoid odors and drying out of food, wrap or cover foods tightly.
