My dehumidifer collect water but the fan blows hot her so it makes the room hotter

It is normal for a dehumidifier to discharge warm air. A dehumidifier is really an air conditioner - a fan blows humid room air across a cold fin coil that causes the moisture to condense on it and drip into a container - thus cooling AND dehumidifying the air. The cool air is blown over the warm coil and discharged out the back. A dehumidifier WILL normally increase the temperature of the room it is in.
You can do the same thing with sitting an A/C unit on a stool in a room. Room air will be drawn in, cold air will come out the front, hot air out the back and water will drip on the floor. And, the room will get hotter, due to what is called "heat of compression" even though you're running an A/C unit.

Hi,
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

Dehumidifier is running but no water is in bucket

Hi,
This often happens because the room is too cool...
warm up the room to 65 or better and you will be okay..

Here is a tip that will help you with basic trouble shooting..

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.

Is it not powering at all? Remove cabinet and check glass fuse on power supply board

Is it running but no water?
Check to see if fan is blowing; if not then thermosenser on fan motor blown

Fan and compressor running but no water? Maybe the room is already dry; if not than probably have coolant leak - not worth fixing

Againg, if theres no moister in the air it wont remove water. if you feel the location for exmaple a basment feels cool when entering , then mosuet exist. dehumidifer will make any location warm when removing the coolnest in the air. within summer hot months it will collect more water than in the winter months. if it does feel cool and machine dont remove the water. call a repair person.

You can check the condenser unit, by touching it. (be carefull of hot surface) if the condensor unit not warm at all we can sure that the dehumidifier is not working, (only fan). The problem may be come from compressor or temperatur limit is not working or cooling agent is finished cause by some leakage on the tube.

Hi..my name is Keith..and your unit has lost is evaporation/cooling capabilities...and its usually do to a freon leak..or the compressor has went out...i would suggest you buying another dehumidifer..i wish i had better news..i hope this has helped and im not always 100% correct..write back with any questions and i will try to help

If your dehumidifier doesn't seem to run often but the humidity in the room is high, try adjusting the humidistat control on the dehumidifier to a dryer setting. If the dehumidifier seems to run constantly, but there's little or no water in the container, there may be a problem in the refrigeration system. Try cleaning the unit. If that doesn't work, you can't repair the refrigeration system yourself, you need a qualified appliance repair technician to do that.

Hope that helps! Should you have any further questions, please feel free to post them here.

By condenser I assume you mean the compressor is running. Is there ice forming on the front coil?
