Typically happens when there is a lot of dust in air. Try cleaning it VERY well, which would mean, shutting it for a few days, letting it melt and dry off, then not only vacuuming it, but then take an air gun (or Air in a can) and get the dust off the coils. Obviously if there is a filter clean it, or replace it.
Check for bent fins on the coil. Most of the newer ones (and yours should as well) have an auto defrost to help with that.
Good luck

I've misplaced the owner's manual on a DEN 500 P. What is a good basement setting for Summer in Central Ohio? Is a manual available on line?


I bought a cheap digital humidistat at Walmart to keep an eye on the humidity in my basement. I hung it on the wall not too near my dehumidifier. I have found that the settings on the dehumidifier are misleading, but I found a setting that keeps my humidity between 40% and 55% (at around 70 degrees), as measured by the humidistat.

What should I set it at


If there is actual water in the basement, any setting will probably cause the unit to run. I would suggest setting it around 60%, and turn it up as you feel necessary. Hope this helps

The fan runs but it does not dehumidify. What could it be?


If the room tempature 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 defost over night.
Only specially made dehumidifers work below a room temo of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensot from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.
