Question about Windchaser WDH928 Dehumidifier

1 Answer

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

My dehumidier pulls out water from the air like it should but blows very hot air while working. Like a furnace. How do I fix this?

    When I first bought it the air that it blew out was only slightly warm not it is hot enough you can't hold your hand in front of it with out getting burned. It's that hot. It never used to do this. Does it need freon charged?

    Hi - "Hot" is a relative term. But if you know that the discharge air is much warmer than it was before - especially if it can burn your skin - then something is very wrong. I am assuming you are cleaning the filter on front regularly. A low refrigerant charge could be causing the high discharge temperature. You should have it looked at for possible repair.

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 have a danby dehumidifier...when I turn it on the fan goes on, but the actual dehumidier does not...the light about the first button does not light up. What Can i do?


It's probably in the wrong mode. This could be from a number of causes including you have not emptied the water chamber.

My dehumidier is not pulling any water into the bucket. Runs fine. About 1 year old.


If the unit is not pulling water into the bucket its probably not that humid in that area anymore. If it aint broke dont fix it.

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.

My kenmore 50 pint dehumidifier 54501 runs but it does not taking in water


You need to determine what's "running". Here's why: There are three things that must be working to extract water. The 'coil' (a finned metal part that needs air to flow across its surface) may be filled with dust and obstructions, so no air can move...then no water. There is a blower motor that must move the air. If it is seized up and not blowing air...very little or no water. The compressor creates condensation from air moving across the coil (like the moisture than forms on an ice filled 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.

The dehumidifier is blow cold air


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.

It is more than likely the compressor is not running, only the fan.
It seams that the humidity sensor is flaky on these units. You can,
operate the unit, by opening up the dehumidifier and unplug the sensor from the main board. The unit will cycle on and off and remove the water from the air.....good luck

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"

Dehumidier Delonghi DH400P not removing any water from the air


Only thing I can tell you to do is to make sure that the evaporator in the back is ice and cold. If the evaporator is not cold the unit will never remove moisture from the air. And if that is the case you have a sealed system problem. The unit may have a leak so there is no gas in it. The compressor may not be working or the humidstat my not be working properly. So check those thigs out or if its under warrenty call for service.
