As the weather becomes hotter and more humid, frost is usually no more than a memory. But it can occasionally make an off-season appearance in your freezer. There are reasons why it happens, even in frost-free models.
Newer refrigerators retain colder temperatures than their predecessors. When the refrigerator or freezer doors are opened—especially in hot, humid weather—moisture can enter the door and cause freezer frost. This may also cause moisture to form in parts of the refrigerator. Defrost heaters in newer models also have shorter run times to meet current efficiency standards.
But don’t let the frosty winter throwback put a chill on your summer. Take these steps to keep your freezer frost-free:
•Arrange shelves and food items in a way that allows air to circulate.
•Don’t overload your freezer full or leave it empty. Both can encourage frost formation. It should be at least half full.
•Make seasonal control adjustments. Your user manual may have recommendations on the appropriate settings for hot and cold weather.
•Seal liquids and high-moisture foods stored in the fresh food section of your refrigerator. This will reduce the chance that the moisture will escape into your freezer.
•Open refrigerator and freezer doors as few times as possible.
•Clean your condenser coils twice a year. Check your user manual for proper cleaning procedures. Cleaning the condenser coils can also save energy.
•Check and maintain door gaskets. A good door seal will help keep the warm, moist air where it belongs—outside of your refrigerator and freezer.
