Our dehumidifer will keep running but it is just freezing up. Then we would have to unplug it and let it defrost. It has been working great up till then. Love the product. How can we fix it.

Turn the Master ON/OFF Switch to OFF, unplug the unit and allow it to thaw out completely. You may want to put some old towels under it, to absorb the dripping water. Once it has completely thawed, remove the bucket, the air intake filter and the face of the cabinet. You should now have access to the coils. Clean them with a mild soap and warm water. Rinse and thoroughly dry the coils. Once they are totally dry, spray a very light film of WD40 on the coils and then wipe off any over spray. Reinstall all the remove parts and test the unit.

Keep in mind, if you are using the dehumidifier in a basement, the air temperature at floor level is colder than at chest level. Dehumidifiers don't work well between 40 & 60 degrees F. (Unless, they are a low temp unit). Any lower, the coils will freeze. Raise the unit up off the floor onto a sturdy table or counter top, that can hold the weight of the unit plus, a full tank of water. In a basement application, doing usually solves the problem of freezing coils.

If after doing all the above, the coils still freeze during operation, the compressor may below on freon and needs to be recharged. Or the defrost sensor on the unit, needs to be replaced.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

Hi, Usually if it is low it will start to freeze up but if you have a freeze control unit then the compressor just won't run much...
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

Hi,

Here is a tip that I wrote that will help you understand why and what you cando with a dehumidifier that ices up.

Dehumidifier is Freezing up and not working

If the air intake filter is dirty, that can affect the operation and cause it to freeze up. Operating in temperatures below 40 degrees will also cause it. Or a low refrigerant level can also cause it. Turn the unit OFF and unplug it. Place some old towels under the unit to absorb any dripping water. Once the unit has completely thawed, remove the filter and clean it. Carefully replace the filter (be sure it's dry) and give the unit a try.

Let's think thru the dehumidification process--

A dehumidifer needs to create a COLD surface, on which to condense the moisture in the room.
If your room is quite cool, it is esily possible that the COLD surface can go below freezing-- Now the water is trapped in the ice-- So-- it has to defrost, to melt off the ice, and start all over again!

Can you move the Dehumidifier to a warmer spot-- maybe near a radiator, or a heat register? -- You will remove much more moisture in that way, too..

Just a question: Most homes are WAY TO DRY during the winter months-- are you sure you need to dehumidify your living area? (Maybe you are drying the basement?-- or a wet area?)

Just seeing if I can help

sounds like your evaporator coil is dirty its the coil where the air goes in

If the room temperature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defrost over night.
Only specially made dehumidifiers work below a room temp of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensor from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

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.

Well your dehumidifer runs constantly. My guess seeing how you bought a 30 pint per 24 hrs. Your house better be 400sqft. It is under sized and humidity need to be 30/50 percent to stop mold growth. It cant keep up its two small 50 pint are for 1000sqft 65 pint is 1300sqft. Upgrade now!!!!!
