Question about Maytag M7DH45B2A Dehumidifier

1 Answer

The dehumidifier is running all the time but not getting the moisture out of the air. It shows 76% humidity but I have it set to 55%. The machine runs all the time but can't get the humidity level any lower. I cleaned the filter a couple of days ago but that didn't help.

My dehumidifier is not collecting water what can i do to fix it? the model #99701


There are several reasons this may be happening. The 2 primary reasons are the humidity extraction level is set to high. Lower it to 35% . The lower the setting, the more moisture/humidity is extracted from the air. The higher the setting, the less if any moisture/humidity will be extracted from the air.
On most humidifiers the fan runs almost constantly while in operation. The idea is to continually move the air around and when the unit senses a rise in humidity, above what you have it set on, the compressor will turn ON to extract that humidity.

The 2nd thing that causes the problem is a dirty of clogged intake air filter. Which is easily solved by removing and cleaning the filter. Which should be done at least every 2 weeks, while the dehumidifier is in operation.

I said there were 2 primary reasons. Actually, there is a 3rd. Not enough clear air space all around the dehumidifier. A minimum of 12" should be maintained during operation.

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

My Kenmore dehumidifier has stopped drawing water from the air to the collection receptical. Fan still runs at high and low speeds.


A couple of things may be happening: The humidity extraction level may be set to high and it can't extract any humidity at that level. Reset/Lower it to 35%. The fans on most dehumidifiers run almost constantly (designed that way) so that it keeps moving the air around. If the sensor picks up a higher humidity level than what it's set to maintain, the compressor will turn ON. This is particularly true, if you operate the unit in continual mode, rather than a timed mode. Also, a dirty or clogged air intake filter, hinders the units ability to remove humidity/moisture.

In addition, operating the unit is ambient air temperature of between 40 & 60 degrees F, causes the unit to struggle to dehumidify the air and the fan to run continuously. Obstructing the air flow around the unit, will also cause it to not function as it should. Maintain a minimum of 12" of free air space around all 4 sides of the unit.

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

Dehumidifier running but no water coming in bucket. it's at 76 humidity. only 2 years old..how do i get it to work right


If you brief description of the problem is correct, you need to turn the humidity/moisture extraction percentage down to 35% and check and clean the air intake filter. Maintain a minimum of one foot air space clearance around the entire dehumidifier and be sure that all exterior doors and windows are closed. DO NOT attempt to remove and clean the filter with the unit ON and plugged in to the wall outlet.

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

Just wanna know how to set the temperature on it


dehumidifiers do not have a temperature control, rather, they have a humidity control. usually you set the humidity control to go off when the level of moisture in the room reaches normal (approx. 25-35% winter;38-55% summer). Best way is to run it at full on for 1 to 4 days (until you know the moisture level is how you want it), then turn the knob until the unit goes off . This will be the ideal setting.

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.

Works well but


Yup, they eat energy.

An electric dehumidifier includes a refrigeration cycle that is very similar to a window AC units and refrigerators. They cool the air in the basement to condense and collect water and remove humidity, heat the air as a required consequence of the refrigeration cycle and dump it back to your basement.

Two sources of humidity in basements include warm outside air that naturally cools due to below grade earth contact and water passing from the ground though the floors and walls and evaporating into the basement. Dehumidifiers do most of the work in the summer when higher temperatures outside enable air to hold more water content.

In the winter, cooler outside air contains less moisture by weight eventhough it may be raining and the relative humidity in basement will be less because the air is warmed relative to the outside. The lower moisture content in the winter also absorbs the water passing through the walls and floor.

From an energy perspective, you may want the humidity set NOT below 50%. This will keep humidity below the level mold desires, but prevents the dehumidifier from doing more work and eating more energy than needed. A cheap battery powered temp/humidy meter left in your basement will help. Sources that include the "mold triangle" (temperature, water & food) often separate fact from expensive hype.

If the dehumidifier doesn't keep up, consider adding a moisture barrier to the basement walls and floors such as Dry-lock and floor paints to ****** moisture entry. Moisture barriers act very similar with water as insulation does with heat. They don't eliminate the need for a dehumidifier, but they reduce the work they do and energy they eat.
