Do Blocked Vents Affect Refrigeration?

If you’re having trouble with your refrigerator, it’s probably time to take a closer look at the vents. These can get clogged by anything that gets dropped into them, like children’s toys or loose change. It’s also a good idea to have the grilles covering the vents cleaned regularly. This helps air flow freely and reduces pressure inside the vent.


A blocked vent in the freezer compartment of your refrigerator can cause the unit to not cool properly. The refrigerator will not be able to cool down enough to keep your foods at their desired temperatures. If you are experiencing a lack of airflow in your refrigerator, check to see if there is anything blocking the vents on either side or on the back. If there is, it may be time to remove the item and see if that fixes the problem.


Blocked vents aren’t just a nuisance, they can also impact the temperature in your refrigerator. Depending on the model, cool air from your freezer enters and exits your fridge compartment via vents in different locations. The airflow might be slightly lessened when the vents are blocked by a large box or bag. If this is the case, it could result in some ice building up on the inside of your fridge. This can result in a number of problems including the loss of important temperature-sensitive foods and beverages. The best way to solve this issue is to not overfill your fridge. Aim to keep the contents about 3/4 full for the best results. If you do decide to overfill, make sure there are no containers in the fridge that will block the vents, and make sure to move them out of the way.

Mold & Mildew

Mildew is a type of mold that is commonly found in damp areas like bathrooms and basements. It is not as dangerous as black mold because it grows on surfaces rather than penetrates them, but it can still cause respiratory problems if left untreated. Mold, on the other hand, is an airborne fungus that can become toxic. It grows in moist areas and produces a strong, musty smell. Mold can be difficult to remove and can even contaminate the air in your home. It is also difficult to control and may take years to die out. If a blocked vent causes the air in your refrigerator to become humid and warm, mold and mildew will thrive. These fungi only need four things to be successful: water, food, oxygen and a temperature between 41 and 104 degrees Fahrenheit.
