My D40 runs OK but I am getting absolutely zero moisture removal. I hear it runing but when I smelled dampness in my basement for a few days I looked at it and discovered that is bone dry. Is it shot? ...

No, it's probably not shot. Just may need some adjustments. Below are the common causes of the problem you're having.

1. The humidity extraction level is set to HIGH. Lower it to 32 - 35%

2. Air intake filter is dirty or clogged and needs to be removed and cleaned.

3. Clear air obstruction. Maintain at least 12" of clear air space around the entire unit, while in operation.

4. The ambient air temperature at floor level is between 40 - 60 degrees F. This is particularly true in basement applications. Raise the unit up off the floor, onto a sturdy table, cabinet, etc, that will hold the weight of the unit, plus a full tank of water. The air temp at chest level is warmer than floor level in a basement. Unless, your dehumidifier is what's called a Low Temperature Model (designed for basements) it may be contributing to the problem. Although, based on all the odds, numbers 1 & 2 above, are going to be the culprit.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

We have water coming from the Air Handler in the basement. We put a new condensate pump on, but that has not helped. Any suggestions

you need to let the air handler dry completely, then wrap it in a insulation blanket, and before you do this listen for it sucking air and tape it for a good seal. What is happening as the unit runs it is not sealed correctly and is causing condensation, you can also purchase a condensation pan and position it under the unit with a drain line and it will stop the water from running all over the basement. Hope this helped Tim

Air intake via hose & window or intake from room only?

Hello artrey3 The answer is yes, BUT the unit will be exausting room/basement air outside ruining any efficency the unit is rated for.Also you will need makeup/fresh air in the basement. The unit exausting air can put the basement in a vacuum/negitive pressure pulling in air from the chimney!

Whirlpool dehumidifier in basement has stopped taking water into

how warm is the basement,if the temp of the basement is lower than say 70 degrees,the unit will not function,true dirty coils can have this effect also and a refrigerant leak on these will cause the same result,if the temp is low,use a fan to move the air and this will help with your humidity problem too

Leaking central a/c unit

All central A/C units have a condensate drain line that comes from just under the evaporator in the Main air supply plenum.

You may have a blockage in that drain line and will have to remove the pipe to clear the obstruction. Try flushing the drain pipe with warm water until it flows easily from the top to the end.

You might have a gravity drain that goes into a floor drain or a french drain along the basement walls. The other typical drain installation is a condensate pump that the water drains into and when the float in the tank is lifted, a small pump turns on and pumps the water (condensate) out of the house either thru a drain hose thru the wall, or into a drain in the basement, etc.

Check the entire drain line and anything connected to it for any possible obstructions and/or blockage.

If you have any other questions once you take a look at your installation, just add a comment and I'll check back within a day to provide more info, based on your input.

I hope you found this very helpful and best regards!

Dehumidifier automatic on and off function not working

Unless you live in a dry environment or place the unit in a hermetically sealed room, it probably will not turn off. As the air dries within the room, more moisture comes in with the air. As long as the air outside of the room is more humid than the room this will be true.
