There is a good thread on this here: http://askville.Amazon.com/dehumidifier-ice/AnswerViewer.do?requestId=3485726
Let's be clear - I am talking about the situation where a dehumidifier has been running happily in one place for a year or more (usually two or three) and then suddenly starts to ice up. There are an amazing number of low probability answers along with just plain crap out there. Here is the answer: The condenser fins are dirty. The dirt stops the water from running off fast enough and so it turns to ice. So, how do you clean the fins? First of all be careful. Unplug the machine before working on it and DO NOT plug it back in until it is completely dry. By the way, if your dehumidifier has a filter, remove it, wash it well with soap and water, dry it, and then try the machine again. If it still ices you are going to have to disassemble the machine. How you do this depends on the make and model. In the easiest case you can remove the front panel. Usually there are either two screws at the top and two at the bottom, or just two at the bottom and plastic hooks at the top. In the harder situation, you have to take off the whole case - usually this is attached by four screws, two on each side located at the bottom edge of the machine. You need access so that you can use a hose with a strong spray nozzle to direct water from the inside of the fins toward the outside. You want to do this while minimizing the amount of water that gets on the fan motor. While you are at it, use a rag and soapy water to wipe all dirt from the fan blades - be careful, the blade edges can be sharp. Working from the back with your soapy water and rag try to get as much soap on the fins as possible. If you work very gently, you can also use a scrub brush but remember that the fins are delicate and you don't want to bend them. Then, using the hose nozzle from the inside of the machine (you will have to work around the fan blades) rinse the fins thoroughly. Now, let the machine dry completely. I generally leave it out in the bright sunshine for a full day. The machine MUST be completely dry before you plug it in again. Then reassemble it and you are back in the dehumidification business.
Air purifiers? Dehumidifier? Ice machine?
Only water should be put into a dehumidifier. If you try to add anything else to it, you might end up ruining the dehumidifier.
It's working too hard. Either get a bigger one, or live with higher humidity. Need to shut it off periodically to let the ice melt. Good luck
There is ice on the dehumidifier coil because it is low on freon. When there is not enough freon in a refrigeration system the inlet pressure to the compressor is lower than design due to lack of gas. Because it is at a low pressure the freon is very cold. This causes freeze-up. If You were to add freon to the running dehumidifier you would see the cold coil thaw, first at the end closest to the compressor suction and then work toward the other end of the coil. When the thaw reaches the other end of the cold coil it has enough freon and no more need be added. Tim Koller
The dehumidifier removes excess humidity from the air.
It is okay to run a dehumidifier and central air at the same time. This will help keep the costs down for the air conditioner. If the dehumidifier is running, the air temperature will cool off quicker and the air conditioner can be turned up a little higher.
Dehumidifier should be cleaned yearly. Proper maintenance is important for the dehumidifier to work properly. anonymous@oola.com

Yes. Do a search for "whole house dehumidifier."
A dehumidifier should be monitored when used to prevent a fire hazzard.
A dehumidifier can cost between $52 to $185. Depends on the brand and the size of it.
You have to add a valve to the dehumidifier in order to put Freon in a GE dehumidifier. The reason you have to add the valve is because dehumidifiers uses a sealed unit.
