My delonghi dehumidifier will not cool the house just keeps blowing warm air and dosnt feel to cool were thinking about giving up on it

Dehumidifiers aren't supposed to cool your house. If anything they generate heat. How it works is, it has cooling coils that it draws air across, which causes the moisture to condense, and be captured. However the heat extracted from the air has to go somewhere, so it just blows out the other side. If you want cool, buy an air conditioner.

Blown fuse

Does the unit sound normal? Does it appear to be getting warm? More than likely the compressor is locked up and it is drawing locked rotor amperage which is high and will trip a breaker or blow a fuse.

I have a Whirlpool dehumidifier model AD050SG0, is it supposed to blow hot air out of the back of the unit?

A dehumidifier is a 'de-tuned' air conditioner. Its job is to remove some of the heat from the air, causing a temperature differential which in turn should make the warm air give up some of its moisture ... just like a AC unit.

To understand the operation, you must accept that you cannot cool anything ... you must remove the heat from it. The heat (energy) must go somewhere ... in the case of a dehumidifier, it goes back into the room. Oh yes, also contributing to the heat is the electric components you are running ... the control boards, the compressor and the fan ... all use power and thus, give off heat.

Should there be heat coming out of the unit? ... yes, if it is running. Don't get mad ... these are things you probably learned in 6th grade science class - relative humidity - heat differential - properties of energy - etc.

My dehumidifier runs but lets out warm air. Is there anyway I can repair myself ? What could be the problem? Help,,, Thanks

The dehumidifier is supposed to be releasing warm air. In order for the built-in refrigerator to lower the coolant's temperature, heat must be removed from it. Thus, that removed heat flows out of the unit. If it's a problem, I would suggest having a fan nearby, or perhaps you could put the dehumidifier in a cooler part of the house. (In case you're curious, try looking for any vents near your refrigerator or freezer, and you'll see what I mean.)

Unit Changes Speed While Running

It may be slowing when the compressor starts, you may want to check the outlet it's plugged in to.

Humidifer is not taking out water. Is there a start capacator for the compressor?

This could be one of several things, we are assuming the air is humid. If the fan is not running and the compressor is, replace or repair fan motor. If the compressor is running, the output line from the compressor should be warm, if not you probably have low refrigerant gas, plugged cap tube or a bad compressor. If it is slightly warm check the evaporator portion at the outlet of the cap tube, it should be cold, probably in the 40F range depending on ambient temperature, if not see above.

Water in the floor

Not sure what you are calling the "collector". Most of the time, problems like this are caused by a build up of gunk at the point where the water, which has condensed and dripped down into a tray, leave the try and is suppose to go either into the water bucket or out the drain hose if that is attached. Because this area gets plugged up, the water has to go some where else, which results in leakage over the side of aforementioned tray.
The best solution is to remove all the covers to get to this drain area and clean it out, but that is a pain to do. I'd suggest trying to run a pipe cleaner or nylon wire tie back up into the area where the water is suppose to leave the dehumidifier on it's way to the bucket or hose. Flushing some water back that way with a turkey baster might work also, but would result in some splashing, causing a little additional temporary leakage.

Dehumidifer runs for about 45sec to 1minute and then shuts off. wqhat would be making this happen

If it does that consistently, then it's likely that the compressor is overheating and shutting down. (It has a thermal overload circuit to prevent a potential fire). Another cause could be a malfunction of the control circuit board which runs all functions of the unit. To check for possible compressor problem, unplug the unit, remove the housing to expose the compressor, plug it back in and power it up. When it shuts down, feel the compressor. It should be warm to the touch, but definitely not so hot that it singes your fingers.

If you find that the compressor is just normal warm, then the control circuit board is shot and needs to be replaced. Check with the merchant or manufacturer for availability & cost. If prohibitive, you're better off simply replacing that unit with a new one.
