How does it work what do I do to operate it


Read the instruction manual and then after you understand that turn it on and set it accordingly. 35% for the humiodity might be a good starting pint.

It has a refrigeration system that blows room air across the evaporator coil then across the condenser coil. The evaporate coil gets cold causing moisture to condense and eventually drip into a collection device.

My dehumidier blows very hot air while working. Makes it hotter than it was before starting. Like a furnace.


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.

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.

Danby DDR-7009-REE. This is my 2nd. The 1st unit did not remove any moisture. The new one removes some but nothing as expected. 1700 sq. ft. basement, air temp 62F, no walls-. Humidity is 50%+ and unit is...


Hi,
It is not working well because of the 62 F temps... the cooler it is in the room the harder it is for the unit to work effectively...

My dehumidifier ices up. It will not remove moisture when it ices up. What can I do and is it under warranty?


Hi,

The coils you see on the back of your dehumidifier are the evaporator. When the unit runs, the coils get very cold. As the fan draws the room air over the coils, the humidity in the air condenses out of the air onto the cold coils. But, if the temperature of the air the fan draws over the coils is too cool, the humidity that condenses out of the air freezes on the coils. To remedy this problem, you can try any of these: Warm up the room the dehumidifier is in. Put the dehumidifier on a sturdy table (the room air is coolest near the ground). Turn the unit off until the room warms up.

Take care.

What could be wrong with my dehumidifier it runs but doesn't draw moisture anymore


does the air feel humid? could be the humidity level dropped and there isn't any moisture in the air. the air passing over the evaporator coil needs to be laden with moisture for the dehumidifier to work.

The dihumidifidier is not drawing water. It is


In order for the Dehumidifier to remove moisture, the coil temperature has to be below the dewpoint temperature. If you check with the weather station and find out what the dewpoint is in your area, then measure the coil temperature or cold line coming out of the coil,it has to be below the dewpoint to get moisture, you can also look at the coil and see if it's wet which will also tell you if the coil is below the dewpoint.

Dehumidifier headaches!


There are three things that must be working to extract water. The 'coil' (a finned metal part that allows air passage) if it's filled with dust and obstructions, no air can move...no water. There is a blower motor that mus move the air. If it is seized up an not blowing air...very little or no water. The compressor uses condensation from the air moving across its coils (like the moisture than forms on a cold glass on a humid day) to extract the water from the air. If it's not working then no water.
So, if there is air blowing out of the dehumidifier the blower is working. If the air is room temp the compressor is not working. If it's real hot air, and the humidifier keeps cycling on and off quickly, the coil is dirty. Those are the 3 things that need to be working.
