Humidity, an excessive amount of moisture in the air, can cause a myriad of issues with your freezer. These issues can range from minor inconveniences to major problems that could potentially warrant expensive repairs. Luckily, there are several proactive measures that you can take to control the amount of humidity that enters your freezer. These measures include:
- Opening the freezer door as little as possible
- Making sure that the temperature of the room or area stays consistent
- Making sure that the freezer gasket is working properly
- Using a Dehumidifier
Keep That Freezer Door Shut
How many times have you opened the freezer door to look for a snack or for something buried in the back? You probably stood there and didn’t give a thought to what was happening when you held the freezer door open for too long. By excessively opening the freezer, you are letting in humidity, and that can be devastating to your freezer and the food inside.
Problems with Opening your Freezer Door Too Much
So what really happens when humidity enters your freezer? When you open the freezer too often, or if you hold the door open for too long, humidity will enter your freezer and cause an increase in moisture.
Since the nature of a freezer is to have a low relative humidity, any type of moisture will cause a build up of frost. This frost can build up on the inside of the freezer, can ruin frozen items and may even cause excessive frost build-up on the evaporator coils. Condensation can also form on the outside of the freezer leading to mildew or mold.
Solutions for Opening Your Freezer Door Less
- Know what you are grabbing from the freezer. This will decrease the duration you have the door open for.
- Organize your freezer effectively. This will allow you to access what you are going in there for more easily.
- Keep an inventory of your freezer. This will allow you to know what is in your freezer at all times.
Keeping a Consistent Room Temperature
Keeping a consistent room temperature is often a very overlooked factor in maintaining a properly functioning freezer. You should always strive to keep your freezer in a room that is no less than 60 degrees Fahrenheit and no more than 90 degrees.
Freezer in a Room Too Cold
If the temperature dips below 60 degrees, the freezer will adjust to equal the ambient temperature and frozen items can begin to thaw. At 38 degrees or below, the compressor will stop operating completely, and a safe freezer environment will be compromised.
Freezer in a Room Too Warm
Conversely, if the freezer is kept in a room or garage that reaches 90 degrees or higher, the freezer will be required to work extremely hard to maintain a low temperature. Typically, the higher the temperature the more humidity there will be.
There is a chance the condenser coils do not get cooled enough and the fridge will be able to achieve low temperatures. There a host of other issues that can be created if your freezer is kept in a warm garage which I cover in this detailed article.
Solutions for Keeping a Consistent Room Temperature for Your Freezer
- Air conditioning. This will allow the units components to properly function.
- Air flow. Use fans and ventilation systems to move the air away from the area that your freezer is operating within.
Functioning Freezer Gasket
The gasket on your freezer, the rubber strip that runs around the freezer door, is the first line of defense against the onslaught of humidity. It stands to reason that if the gasket is damaged or broken, then humidity has a greater chance of causing havoc inside your freezer.
Solutions for Ensuring Your Gasket is Working
- Perform a visual test. Closely examine the gasket for tears, rips or worn out areas. If the gasket has minimal damage, you can usually repair the area with rubber cement. Once it’s dry, that should do the trick.
- Perform the dollar bill test. Take a dollar bill, put it on the edge of the freezer door and close the door. Give the dollar a tug. If there is no resistance, then the gasket most likely needs to be replaced.
- Clean the gasket. Mold and mildew can build up and cause problems with the freezer gasket. You can easily fix this issue by taking an old toothbrush or a cloth and cleaning the gasket with a solution of one quart warm water mixed with one tablespoon of baking soda. Rinse it well and wipe it dry. This will also clean out any build-up of grime that has accumulated on the gasket.
Use a Dehumidifier
It stands to reason that if humidity is detrimental to a freezer, then the use of a dehumidifier would be an excellent idea. A dehumidifier is basically what it sounds like. It takes the moisture out of the air, turns that moisture into water and stores it in a collection compartment.
This is important when used around a freezer because it will help reduce the amount of humidity in the air, and less moisture will enter when the freezer door is opened. Dehumidifiers are not expensive to run, and they don’t use a lot of electricity.
They are excellent for when you have your freezer in a garage or basement, and there is a lot of humidity in the air. Try to place the dehumidifier in or near the center of the room for the best results.
Humidity, something we all complain about during the summer months, is very detrimental to the overall health of your freezer. Fortunately, most humidity issues can be fixed using the above points.
