If you’ve ever opened your freezer to find a thick layer of frost covering everything inside, you know how frustrating it can be. Not only does it make it difficult to see what’s stored inside, but it also affects the efficiency of your freezer. But why does this phenomenon happen?
There are several reasons why your freezer may be frosting over. One possible cause is a faulty door seal. If the seal is not airtight, warm air from the outside can enter the freezer, causing the moisture in the air to condense and freeze on the surfaces inside. Checking and repairing the door seal can help prevent this issue.
Another reason for frosting over is a malfunctioning defrost system. Freezers are equipped with a defrost system that periodically heats up the evaporator coil to melt any frost that has accumulated. If the defrost system is not working properly, the frost will continue to build up and eventually cover the surfaces inside the freezer.
Additionally, overpacking the freezer can also lead to frosting over. When items are tightly packed together, air circulation is restricted, and cold spots can form. These cold spots are more likely to attract and accumulate frost. Properly organizing and spacing out the items in your freezer can help improve air circulation and reduce frosting.
