Question about Maytag M7DH45B2A Dehumidifier

Open Question

I Purchased a Delonghi CF08E Dehumidifier and the "Humidity switch" doesnt appear to work. I have a hygrometer and it shows the room at 50% to 55% humidity but when selecting selecting 60% or 70% on the humidity switch, the unit continues to run.Ive even selected 50% when the hygometer shows 55% and watch it drop to 47% and the unit still runs. Instructions say that once the choice of 50%,60% or 70% is chosen, the unit should shut off automatically once the humidity drops below the chosen setting. This unit is brand new and has done it straight out of box.

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

Your bucket full switch may be defective. If you are capable, bypass it since you are draining to another place other than the bucket.

First, make sure the rectangular filter on the back side is clean so air can flow over the coils freely. Try to place the dehumidifier on a table or something to get it off the floor. (floor level is cooler than head level) If you still have icing issues, replace sensor. (part # WK23X10011 )

I cant change humidity levels


Hi Ra Ma,
After you have set the desired humidity, the readout will display the actual room humidity. It has a built in hygrometer which will be on the display while it is running.
You change it and it shows the actual levels.

See page 5 on manual.

My dehumidifier does not seem to be working properly. I can't find the manual to tell me what the settings should be. Would appreciate your help. It is a DeLonghi DE400P. Thanks Shirley


What is the specific problem? Is no water being collected by the dehumidifier or do you have another issue?

Make sure that the dehumidifier is in a room in the operating temperature range (at or above 44 degrees F). Make sure that the room door and windows are closed and that the room is not larger than 2200 square feet. Make sure that the collection bucket not full and is properly seated in the dehumidifier. Check and clean the air filter on the dehumidifier. (Vacuum the filter or rinse under running water three times. Then wait until dry to replace it in the dehumidifier.) Look at the coils of the dehumidifier. If you have ice on the coils, defrost the unit (turn off, unplug and wait for it to melt). If the ice reforms quickly, you may have a leak in the coolant system. Then the unit needs repair.

Next make sure that you have good air flow around the dehumidifier and that the desired humidity set point is lower than the humidity of the room.

On a dehumidifer, you set the relative humidity, not temperature. Normally the humidity should be set within 40 to 60 percent humidity.

Compressor sounds as if its on, the fan is on, but water is not extrated from the air


If the room air is less than the set air then there is no water in the bucket because there is almost no humidity in the air. If it is winter, there is likely not enough humidity in the air to have water collect in the bucket. A dehumidifier will only pick up humidity out of warm air. If you are running a dehumidifier in your basement in the winter, the room may be damp, but too cold for the dehumidifier to pull out the humidity. Try running the unit in the bathroom after having a hot shower without the bathroom fan on. If working correctly the unit should draw water.

In addition, check to see if the air filter is dirty and/or blocked. Also, the room temperature might be too low, (below 15.5 C/ 60F) and finally, check to make sure that there is no obstruction to the unit, that might be causing poor airflow circulation.

I hope this helps you to troubleshoot and solve the problem.
