I have a Crosley dehumidifier that sits on a shelf in a wall. The back side of the unit (air intake side) is open to my utility room that is completely enclosed. The front side of the unit faces my finished basement. I have a drain hose hooked up to the back. Lately (over the last 2-3 months) I'm noticing that the drip pan has alot of dust and the coils don't seem to get cold anymore. Is it just because the intake room is really that dry and maybe I should install some ventalation so air from the finished portion of the basement flow in or has the unit just stopped working?
If you can verify that the compressor is still active (is there a noticeable hum or buzz and / or do the room lights slightly dim during power on?) then the most likely problem is a loss of freon. if the compressor never turns on, then a faulty humidistat is likely...an electrician can run a test of this by "jumpering it out" to force on the compressor motor.

IIt may very well be that the the air intake filter needs to be removed and cleaned. But, before doing this, turn the unit OFF & unplug it. Allow the unit to completely thaw, before removing the filter.Never operate the unit without the filter in place, As this could damage the unit.
This may be caused by running the unit in continuous mode, rather than timed mode. The heat is generally is generated when the defrost mode cycles on, to defrost the cooling coils. This happens more frequently, if the air space around the unit is obstructed or it's operating in a temperature range of 40 to 60 F. Cleaning the air intake filter at least once a week, can help solve this problem, too.
Maintain a minimum of 12" free air space around all sides of the dehumidifier. Use a timed mode rather than a continuous mode. Make sure the room is within the proper operating temperature range and clean the air intake filter weekly.
Hope this helped you troubleshoot and solve the problem.
Without a Model Number or Part Number it's hard to help you. But here are three links, where you can find the float switch, if it's still available. You'll definitely need the Model Number to find anything.
Since it has been working well for 4 days, it may be a case that the unit needs to reset itself. To accomplish this, turn the Master ON/OFF Switch to OFF. Unplug the unit from the wall outlet and wait 12 - 15 minutes. Then plug the unit back into the wall outlet and turn the Master ON/OFF Switch to ON. Set the controls as you normally do. Hopefully, that timeout allowed the unit to reset itself. Also, check to make sure that the water collection bucket is installed properly and is making good contact with the safety switch.
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.
Pull out the water collection tray. You will see a small pipe (about 1/2" diameter) in the top of the area where the tray came from. This is the "drain" that fills the tray. Connect a hose to this pipe and run the hose to a floor drain if you have one. I used a section from an old garden hose for my unit. There also may be a small opening in the back wall of the dehumidifier to route the hose more aesthetically.
