My dehumidifier model number FAD704DUD is blowing hot air. What is wrong with it?

Hello Roberto, thanks for your post!
From the information you have provided you would like to perform a factory reset on your Frigidaire dehumidifier. The best way to reset your dehumidifier is to disconnect power from it for at least ten minutes. I hope this information is helpful to you. -Matt

Good Afternoon Friend,

I understand that the bucket fills with water and overflows on your Frigidaire dehumidifier, model# FAD704DUD. Please make sure your dehumidifier is installed on a level that will support it with a full bucket of water. If the dehumidifier is moving when it fills with water then this could possibly be the cause of the bucket overflowing. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your appliances status has changed successfully. Hope this is helpful.

-Best Regards-

It sounds like not enough air flow. clean the filter. I would suggest unplugging it and let it set for a day to dry out then replace filter and clean the air path including coils.

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.

I had the same one and yes it is pretty warm air that blows out of it

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

Is it collecting water? The air coming out the back top half should be cool/warm. It will be a little warmer at the bottom near the compressor.

Again, if your model is one that can be used in cooler temps so as not to ice up, the heat prevents this.

A common problem - low on refrigerant. Unfortunately it's not a simple fix. Check your warranty to see if you're still covered for "Sealed system repairs"
