Why did it stop condensing water?


The condenser can only remove humidity if there is still humidity in the air. What's your Relative Humidity? A manual sling psychrometer is cheap enough to check it.

My DH40 unit kicks on and off very frequently while the fan is constantly running. What do I need to do?


Toni, this sounds like the humidity extraction level is set to high. Lower it to 32 - 35%. The fan is running in an effort to recirculate the air. If the unit senses a rise in humidity above the level you have it set on, the compressor will turn on to extract the rise in humidity. That's why I think your level is set to high.

Hope this helped you to troubleshoot and solve the problem.

I have a GE AHH50LMG1 dehumidifier. It is less than 2 years old. When I turn it on, it displays 20% RH. The fan runs but the compressor does not kick in. I assume that is because it thinks the humidity...


Hi,
It could be just the sensor, but not likely... many times it is the circuit board that goes bad, making the repair almost prohibitive.. as the circuit board, if you can find one, is often half or more the cost of a new unit...
But you are correct... if the unit thinks the humidity is 20% then it will not bring on the compressor...that is what is happening...

My dehumidifier kicks on for about 20 seconds and then kicks right back off!


What sometimes causes that, is that the water collection bucket is not sitting in the unit properly/tightly. When the unit turns ON, the vibration causes the bucket to move and lose contact with bucket safety removal switch. Try removing the bucket and reinstalling so that the top and bttom of the bucket fit squarely into the holder and the bottom doesn't tilt downward.

Also, check the humidity extraction level. It may be set to high. Lower it to 32-35%.

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

Is this a low temp model, as it is not dehimidifiying but fan is running


The model you have was made by Fedders for Maytag. The fan runs as a recirculating fan, to continually sense when the humidity level rises, above what have the unit set on. Here in, may be the problem. If you have the humidity level set higher than 50%, that's pretty high and the unit want remove much if anything. It will just continue to maintain that level. Keep in mind, the unit's humidity level must be set LOW, for the compressor to kick on and start removing humidity. By low, I mean 35% or minimum, if your unit does not have an LCD display.

I must caution you, that there is associate on this website that would tell you, that the level should be set on Maximum. Believe me, that simply is not the case. That is, unless you want your home to be hot and humid.

Hope this helps you to troubleshoot and solve the problem.

Humidity sensor reads to low and does not kick the machine on. The readout seems to always be at 20% and wont kick on till 35% Is there an adjustment i can make to tuen the unit on?


It probably doesn't need adjusting, It's simply a case that 20%, there's not enough humidity for the sensor to read. But, at 35% there is. I'd say, your dehumidifier is working as it should.
FYI - there is no adjustments to change the factory settings.

Hope this helped you, chu.

20% humidity reading


Hi, I just cleaned my dehumidifier and had the same problem as you. I used a spray water bottle and was not aware that the humidity sensor was being soaked. Very stupid of me!! Luckily I have two same dehumidifiers and used the other sensor to replace the one that I so stupidly ruined, and behold my machine worked again. Now I have to buy another sensor. To make sure we are talking about the same thing, my sensor is white,about 1 inch by 1/2 of an inch. It as 4 wires connected to it. To access it you remove the water tank, you will see 2 screws. Remove those, and pry the front panel loose. Be careful the top of the panel is held by two plastic hooks, they break easy. The sensor is located on the right side just above the radiator, under a produting oval lip which as foam around its rim. The wire colors are red black blue and yellow. Good luck Herman
