Make sure the filter is clean and plenty of air comes through, when coils freeze it is usually caused by low air flow coupled with lots of humidity and low air temperature in the space to be cooled. Clean the filter, fan and gently brush all dust and debris from the intake of the cold coil and retry it. If the basement is already cool and you are trying to dehimidify you should use a dehumidifier that features defrost controls.

Coils freeze up. completely blocked. have to shut off to thaw coils. located in basement.


After the unit is totally thawed and dried, turn the unit Off if you haven't already and unplug it. Remove the filter and clean it. If it's really dirty wash it with warm water and dish washing liquid, thoroughly rinse it and allow it to completely dry, before reinstalling. DO NOT operate the unit without the filter in place.

Because the air temperature in a basement is colder at floor level, than at shoulder level, this caused the coils to freeze. Dehumidifiers do not work well at temperatures at or below 60 degrees F. That is, unless, it's a Low Temperature model, designed especially for basement applications. Obviously, yours isn't a Low Temp model.

To overcome this, place the unit up on a sturdy table, counter top, etc, that can handle the weight of the unit, as well as a full bucket of water. The higher off the floor the better. This way, the ambient operational temperature will be higher and the coils will have less of chance to freeze again.

I would suggest that continue to monitor the unit and if you notice that it's doing more than a little frosting on the coils, turn the unit OFF immediately. A little frosting is normal and the deforst mode should kick in and thaw the coils. When this happens, the compressor should automatically shut OFF, but the fan will continue to run. Once it's defrosted, the compressor will start again, if necessary.

I hope this helped you to troubleshoot and solve the problem. Please let me know.

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.

Dehumidifier Problems and Dehumidifier Troubleshooting


If you have a dehumidifier that is not working correctly you have many things that could be causing it not to work. Here I will give some of the common reasons why it could be giving you problems.

0ebf56c.jpg
  1. The coils in the back are frosting up.

The dehumidifier works by drawing the room air over a very cold coil. The trick is to keep the coil as cold as possible to make it pull water out of the air by making it condensate on the cold coil. If this coil becomes too cold, then the water freezes on the coil. The freezing can happen if the air temperature in the room is too cool and does not keep the coil warm enough. Raising the humidifier up off of the floor onto a table can help. The air temperature is often a bit warm the higher up you get. Make sure that the filters are clean if your unit has one. Restricted air flow will make the problem worse. Providing more heat to the room will help also. Most units will not work in a room with temperatures below 68 degrees F.

  1. There is no air moving over the coils.

This can happen if the fan motor becomes stuck or burns out. If it becomes stuck you can sometimes get it running by working a lubricant into the bearings. WD-40 first, and then a good motor oil. If the motor burns out it will need to be replaced.

  1. The indicator light is on and the unit will not run.

This shows you that the bucket is full and needs to be dumped. If your unit is working correctly and the air is very damp you may only run a few hours before the bucket becomes full. This also can happen if the bucket is not seated in it’s spot correctly. There is a little switch that will not let the unit run if the bucket is not place exactly right.

  1. There is no water being produced.

This can happen if the air is very dry and no water can condensate from the air. Check the coils to see if they are cold to the touch, actually they should be very cold, like almost freezing. If not then the refrigeration system of the dehumidifier has gone bad. To repair that you will need a person certified to work on refrigerant systems with specialized equipment. In many cases the costs to repair the refrigeration systems will more than the cost to replace the whole unit.


This should give you a brief overview of the problems that you can have with a dehumidifier and some of the things that you can do to help get things working.

The coils keep freezing on my gold star dehumidifier


Try turning the setting down lower in order to help the unit cycle on and off, rather than have to run constantly.

It could be that your situation requires more than one dehumidifier for the space you're trying to cover with this one unit. These units are not designed to operate 24/7 without cycling on and off frequently.

The situation you're experiencing tells me that you have either an extreme amount of moisture where the unit is placed, or the area is much to large for just one unit to handle. If you can issolate the unit to one area by closing a door, etc. if that isn't possible, you'll likely need another dehumidifier to help reduce the load on this one that's freezing up while helping reduce the amount of moisture in the area.

If that doesn't help, please provide more details about the area the unit is being used in and the size of the room, etc., so I can further assist you in solving the problem. Thanks!

Amana 30 (looks like dk25) unit runs but coils freeze up


Most dehumidifiers have a defrost mode in which the compressor is turned off to give time for the frozen water to melt. The freezing problem ocurrs when the unit is used in very cold weather. Check your manual to see if this unit comes with automatic defrost mode. If it does, it would appear that it is not operating correctly and you can request warranty service. If no defrost mode is available, then your only option is to heat up the room in order to use the dehumidifer within its limit of operation. Some units can operate as low as 36 F, but most units cannot go that low. Find out what your unit's specs are from the manufacturers web site.
