Controlling the degree of moisture in a freezer is important to make sure that it keeps functioning optimally. This applies to both standalone freezers and freezer compartments in a fridge. Even at the low temperatures of a freezer, moisture can still build up over time, causing problems in and around the unit. Excessive moisture buildup inside a freezer can lead to a lot more ice, requiring that you defrost the freezer more often. Mold may also start to grow on the outside of the freezer and the wall behind it. Fortunately, there are a few easy ways to control the moisture buildup in a freezer. These methods are well within reach of any home owner or DIY enthusiast.

Step 1 – Use a Dehumidifier

In some cases, the best way to control moisture in a room and everything in that room is by using a dehumidifier. These are commonly used in places such as outbuildings or basements where damp can be a problem. A buildup of moisture in the air can quickly cause problems, ultimately causing damp to build up in all parts of the home, including the frame. This needs to be prevented at all costs before it causes serious damage. Having a dehumidifier in the room is necessary if the atmosphere is fairly humid and there is quite a lot of moisture consistently in the air. For places such as basement bars, your freezer will be subjected to this atmosphere, but having a dehumidifier present will help to make it run optimally. Dehumidifiers are easy to use and do not use a great deal of power. They convert moisture in the air into water which is gathered by the machine and emptied periodically.

Step 2 – Check the Freezer

The next thing to do is to check the freezer itself to make sure that there are no problems causing it to run below standard. Make sure that the door is always kept shut to maintain the temperature inside. This is very important regardless of the climate. Always think about what you want to get out of the freezer before opening the door, rather than constantly leaving the door open. To make using the freezer more efficient, make sure that everything in it is properly arranged. Having everything well-organized will prevent you from needing to open the door as much.

Step 3 - Replace Door Seals

You may also need to replace the sealing gasket around the freezer door. If this is not providing a solid, reliable seal, then moisture will be allowed to get inside the fridge which will, in turn, cause an excess in moisture buildup. Having an inefficient seal around the door of the freezer is rather like leaving the door ajar altogether. You should be able to find a replacement plastic or rubber seal to place around the freezer. This will allow you to repair and optimize it without spending too much money.
