Faced with the cold stare of an iced-over dehumidifier, you may be wondering how it works. Luckily for us researching this article was simple! Understanding some basic science will help explain why yours has frozen over and what we can do about that?

The first step in solving any problem is understanding what makes them tick which means taking a peek at their inner workings. Why is it so important to have a fully functioning dehumidifier?

A machine that doesn’t work can cause all sorts of problems in your home. It might damage furnishings, create mold and dampness which are uncomfortable for people with health conditions like the asthma-the list goes on! In this article, we will show you how to avoid these issues by knowing when humidities become excessive.”

How a Dehumidifier Is Supposed to Work?

The most important thing to know about dehumidifiers is that they work in the same way as air conditioners but without making your house cooler. The unit removes humidity by running water through coils of tube-like material which causes moistness on its surface and then pulling it away from there rather than cooling off like an AC does (which also means you don’t need any special plumbing).

Why Does Dehumidifier Freeze Up

When the high-pressure refrigerant from a Freon leak cools down and becomes less harmful, it circulates through condenser coils where an outside fan blows air over those hot tubes to transfer heat into your home or business.

An air conditioner is a machine that makes cold weather in your house tolerable. It consists of many small machines and coils, all working together to keep you cool during hot summers or warm winters! The first step involves the passage over these very cold metal blades which cause themselves to become chilled by contact with warmer ambient temperatures while simultaneously removing moisture from surrounding environments through evaporation making our living spaces both cleaner clearer too!

Next, this liquid refrigerant goes back into an expander where its energy Payoff becomes converted into mechanical power needed for compressing gas inside. In a dehumidifier, the hot and cold coils are mixed together. The entire purpose of this device is to remove moisture from the air but it doesn’t cool or change its temperature as soon as you pass over those evaporator blades on your way out they’re just there for decoration!

Humidity is the enemy, but you can’t kill it with a gun. You’ll just have to find other ways of taking out your frustration on its behalf like throwing things or hitting something hard (not us). But when humidity does strike back in unexpected moments like right now! It’s best not to get too frustrated because we all know what happens next: The air from around me hits those very cold coils inside this little box called an evaporator and causes them to sweat! see? It works exactly how our bodies do; by forming moisture on surfaces that are colder than theirs.

Why Does My Dehumidifier Freeze Up?

When it comes to fixing a dehumidifier, the first thing you should know is how they function and what causes their dehumidifier coils to freeze up. When you need to dehumidify your home, look no further than a basic unit. It includes everything from cold evaporator coils and warm condenser ones so it can easily climates of all types!

This is great because not only does this type provide relief when things get too dry but also prevents the growths associated with high levels of humidity levels such as mold spores which are bad news if they pop up anywhere in our house

The fan motor helps keep things running smoothly while maintaining an optimized environment for whatever task at hand be that cleanup duty after an extended rainstorm. Your dehumidifier is a really cool machine that works by pulling air into its vents.

The cold metal coils in this case condense and turn into water droplets! You can choose whether or not you want these stored inside of your home, but either way, they go through an ingenious design to make sure all moisture gets eliminated from the room before entering pipes which carry away any excess rainwater outside (and then eventually towards lakes/streams).

When the dehumidifier freezes up, it’s not just a pesky problem. The cold air can damage your equipment and cause flooding in homes with low ceilings or younger children who may push their toys under furniture for safekeeping during winter months without realizing what they’re doing!


So how can you avoid your dehumidifier from icing up? The answer is quite simple. Make sure that the room it’s in stays at least 65 degrees Fahrenheit! If you have a cold winter and your dehumidifier stops working because the water vapor freeze around its coils, it’s not just an inconvenience.

The lack of moisture in the air can cause health problems for those who suffer from asthma or other respiratory issues caused by viruses such as flu virus which thrive inside wet environments like these frozen droplets found on window panes during colder months when they’re covered with frost Every year we see people die due to them going out after Christmas until April comes along again this time last year.

The dehumidifier is not very happy when it’s used in a room that’s cooler than 60-65 degrees Fahrenheit. The evaporator coils will get too cold, and before water droplets can drip into their collection tubs they freeze on the metal surfaces; soon there are big solid lumps of ice blocking off flow through your machine!

Dirty Air Filter

The common reasons for a frosted dehumidifier are when there’s an excessive amount of dirt and dust on the air filter, which prevents proper circulation. This can lead to sweating evaporator coils that turn into solid masses of full-color ice!

You may not have even realized that your dehumidifier has an air filter! If you don’t know what one is, then make sure to get one.

The filters are very important for keeping dust out and preventing corrosion inside the machine before it gets into places where water can freeze due to its cold internal coils which lead to frosting up during winter months when things tend to be cooler than average levels of heat loss per inch exposed surface area (HLC).

Your dehumidifier’s air filter is one of the most important parts. Without it, you’ll be subjecting yourself and those around you to dangerous amounts of moisture in your home or office space!

Make sure that this essential component has been cleaned regularly so as not to cause any problems with performance to consult the user’s manual for instructions on how often they should change their own filters (and if possible try installing an annual cleaning service).

Dirty/Clogged Condenser Coils

Your dehumidifier’s condenser coils are right next to where the air enters, so they get dirty really easily. If you don’t clean them often enough then eventually there will be more dirt and pet hair in your house than ever! The result? Your machine starts freezing up because it can’t circulate proper amounts of moisture through its filter anymore – not good when we want our homes at peak performance levels every single day.

If you decide to clean the condenser coils, be careful when removing the cover. Unplug the unit first and only use screws or lifts that are designed for this task! For newer models with digital touchpad controls, it’s important not to damage them so as to prevent any problems later on down the road.

The condenser coils have delicate, thin fins that need to be cleaned carefully so they don’t get bent or folded over. Vacuum cleaners with long snouts and soft brushes are helpful for this job because you can use them without damaging the coil’s surface finish!

How to Fix A Dehumidifier That’s Freezing Up( Step by Step)

Does your dehumidifier seem to be running constantly? It might not have enough water in its tank. There are two things you can try before calling for help: checking that there’s been at least an hour since it was last filled, and adding more drops of liquid until they start flowing out again on their own (this may take several tries). If these remedies don’t work- or if the problem continues after addressing all possible causes then something else must’ve gone wrong!

Step 1: Humidity Control

Your dehumidifier is running because there’s too much moisture in the air. You can fix this by setting your unit higher than normal so it doesn’t continue to run once dry out making sure you have plenty of airflow through coils during operation will also help with icing problems!

Step 2- Check the Room Temperature

If your room temperature is lower than 40 degrees F., the dehumidifier will definitely freeze up. This can be an indicator of this if you see frost on all sides and evenly across its surface. It’s also possible that raising their blower wheel/ Heater may solve any problems with freezing-up so long as they’re set properly beforehand! You can also adjust a temperature sensor in your room. Also, check the flow of air through it.

Step 3- Wheel or Fan Blade Sticking

The fan on your dehumidifier could be blocking, which will cause it not to push air through the coils properly. This can lead to ice buildup and other problems since moisture stays around longer than normal! To fix this issue check if there is any dirt or other objects stuck in between where you think blades should go; use a soft brush (or pencil) with water immersion as needed-maybe even take advantage of those pesky rainy days while we’ve got them.

Step 4 – Set unit far From Wall

Make sure you set the dehumidifier far enough from any walls or objects so that it has plenty of room to operate. If there is not enough space for air temperature, then this could cause freezing up of your appliance!

Step 5- Check if the Fan Working or Not

When you are looking for any dehumidifier problems, it’s important to check if their fan is working. If they don’t blow airflow across the coils when turned on and supposed to be operating in order to prevent freezing up!

Step 6 -Filter Cleanup

If you want to make sure your dehumidifier is running at peak performance, follow these simple steps. First of all clean the filter if it has one and then vacuum or spray away any accumulated water from inside with a garden faucet until there’s nothing left behind but air!

Step 7- Vacuum the Coils

Have you noticed your dehumidifier is taking longer to dry out? This could be due to dirty condenser coils. To clean them, first, unplug the machine and remove any screws that secure its outer cover (there may not even be an inner housing). Next, gently wipe down all sides of each coil with a cloth or paper towel until they’re free from grime before replacing their respective parts in order once again; making sure everything goes back together smoothly this time around!

To clean your air conditioner, first, allow all ice to melt and excess moisture to evaporate. Next use a brush attachment on the vacuum cleaner carefully remove any dust buildup around or inside of it without damaging its coils!

There are a few different ways you can try and clean your unit. If the coils aren’t very dirty, simply vacuuming them might do the trick; however, it’s best if they’re completely dried out before putting everything back together and plugging in! One thing I always recommend doing when trying new cleaning methods for any appliance is spraying some water on those pesky dirt stains (and then wiping down) because this usually gets rid of anything partially radiates onto my surfaces rather quickly – much better than chemical cleaners which could damage

Step 8 – Test The Unit

Try turning on your dehumidifier and see if it freezes up again.

Step 9- Make a Decision

Tossing your dehumidifier? Ready to get a new one next week! Well, before you do that there are some things I think you should know. First off- make sure the machine seems right by checking for leaks and making note of when it was last serviced at an annual appointment with someone who knows what they’re doing (or has experience working on these kinds).

Secondly – don’t take any chances when charging up because sometimes too much gas can cause damage internally which leads me directly to my third point: always check oxygen levels first; ventilate cells if necessary after adding refrigerant oil/refrigerants.

Wrap UP

There are many possible reasons why your dehumidifier may have frozen up. We recommend that you carefully look at the way it functions to figure out what’s causing this problem and fix any underlying issues with water flow or other factors before they cause more damage!

What’s that? You don’t know how to fix a broken air conditioner, but do you think it needs some fixing? Well, then this article is perfect for your needs because we’ll take an in-depth look at all of the parts and what they do.

We also have tips on where things might be going wrong with them so when something breaks again (and trust me; these machines will break sooner or later), hopefully, our guide can help save time by not having anyone else go out looking around town trying to find someone who knows exactly which screw goes into which hole!
