HI HAVE GOT A SWAN SH3010 DEHUMIDIFIER BUT THE COIL KEEPS FREEZING OVER WHAT AM I DOING WRONG?


Nothing.That's how it works. The coil gets cold. The moisture(water) in the air freezes to the coil. The coil then gets warm and the ice melts, dripping into the bucket or out the drain hose.

Dehumidifier is Freezing up and not working


If you are having problems with your dehumidifier freezing up them here are a few things that you can check and also a few things that may help you.

First check the ambient temperature of the room at the level of the dehumidifier. If it is below 65 degrees and you do not have a special low temperature dehumidifier then you are asking for trouble. Most units are only designed to work in temperature 65 or higher and will freeze if they are working at lower temperatures. Some even will not work well below 68 degrees F.

Many dehumidifiers will shut off when the coil starts to freeze to let them thaw, then they will restart when the coil is warm enough again. This can take an hour or so. Some will not shut down the compressor and when the dehumidifier coil starts to freeze it reduces the air flow and only compounds the problem.

Check the air flow over the coil. If the coil becomes dirty or the fan motor stops or even slows down a bit, you will get freezing. The dehumidifier is very dependent upon the proper amount of air going over the coil to keep the coil warm enough to not freeze. Any restriction will cause problems.

The final and worst thing that can happen is for your dehumidification unit is to develop a slight leak in the refrigeration system. This will cause the coils to run even colder then they would normally and this will create the same problems. If everything else check out then you may have to have the refrigeration system checked by a professional. The problem with this is that many of these units only cost a few hundred dollars and a service call can soon add up to more then the unit is worth.

Some things that you can do to help out a dehumidifier that is freezing up are:

Raise the temperature of the room and provide a bit of heat for the room as the dehumidifier is actually a very small A/C unit.
Raise the dehumidifier up off of the floor… the air is usually warmer when you go higher up in the room, hot air rises.
Clean the coils off so that the air can flow through them easier and keep them warmer.
Make sure that the fan motor bearings are oiled and that the fan is running freely. Even a tiny bit of resistance will slow the fan enough to make a difference.


By checking all these things out and making some small changes you maybe able to make your dehumidifier work much more effectively.

Often times, a clogged filter will cause them to freeze up. Because, it's not getting enough air into the system to warm the coils. If you haven't cleaned the filter recently or regularly, that is more than likely the problem. Other than that, the ambient room temperature can play a role in it. If it's cooler than 41 degrees, the humidifier struggles. Same is true if it's over 93 degrees.

Hope this helps you solve the problem.

This summer I have ice build up on top of the unit. I have a drain hose so the bucket is not full. I have cleaned the air filter. I have also removed the front grill and used a fine brush to remove dust...


Hi,

The coils you see on the back of your dehumidifier are the evaporator. When the unit runs, the coils get very cold. As the fan draws the room air over the coils, the humidity in the air condenses out of the air onto the cold coils. But, if the temperature of the air the fan draws over the coils is too cool, the humidity that condenses out of the air freezes on the coils.

To remedy this problem, you can try any of these:
Warm up the room the dehumidifier is in.

Put the dehumidifier on a sturdy table (the room air is coolest near the ground).

Turn the unit off until the room warms up.

Take care.

Iced over


I thnk you are expecting too much from your machine. DO NOT RUN IT WHEN IT IS FROZEN!

This is what I would do. Slow down the process. You shuld be agle to select the % humidity you seek. Set it high, say 90. Get another fan in your basement working to sirculate the air. When your machine has achieved this goal without excessive running and freezing, go to 85% or 80%. It may help if you direct a small fan at the coil that freezes.

Are you certain your machine drains properly? Hose to a sump pump? Is the sump pumping properly?

And lastly, you may want to add a second machine. I operate two in my basement and they keep it 50% in the summer. My basement is about 4000 cubic feet.

I hope this helps you

Humidifier coils freeze


I believe a dehumidifier is supposed to operate in temps above 60 degrees. Even though your house is warmer than that, the air entering the dehimidifier may be getting into that range due to it being on a basement level etc. This is perfectly normal and is not a malfunction with your humidifier.

Your options are to either place the dehumidifier closer to a heat source in order to keep the air which is entering warmer. (I've even heard of someone placing a light bulb in front the unit during winter to warm the air slightly as it enters). Because the dehumidifier's coils get cold in order for it to collect moisture from the air, if they are freezing, giving the unit a rest for a few hours every few hours may allow the coils to thaw in between and prevent them from reaching freezing temperatures while running. You could use a timer to accomplish this, but you'll want to insure that it's a commercial grade timer in order to handle the electrical draw that the dehumidifier requires.
