Question about Maytag M7DH65B2A Dehumidifier

1 Answer

My Maytag M7DH45B2A Dehumidifier turns on and runs for 30-60 seconds, then turns its self off even though the humidity level is set below what humidity is in the air. The full light does NOT come on so it has nothing to do with that area. It just turns on and off constantly without taking the humidity out of the room.

    Nope, I turn it down to 35.... it runs for a while, turns off while still showing the humidity level at 55 or 60...

  • lpdofficerbr May 28, 2009

    I am pretty sure its not the bucket... I guess I will start with the humidistat! Thanks for your help!!

    What happens if you set the humidity level to as low as possible? Will it run constantly then as it should?

Dehumidifier runs from low to high.does not keep same fan speed.


If you are operating the dehumidifier in continual mode, this is normal, based on the humidity extraction level you have the unit set on. It senses when there is humidity to remove and speeds up. When it has reached the level you have set it for, it slows down and keeps the air circulating, until it senses a need to speed up, again.

Hope this helps you. Thanks for choosing FixYa.

Full light is on and therefore it will not run even though there is no water in the container.


Generally, when this occurs, it is a result of misalignment of the placement of the water collection bucket. Remove the bucket, an reinstall it into the dehumidifier making sure that it makes proper contact with the bucket safety trigger switch. If you do this while the unit is turned ON and the humidity extraction level is set low enough, the compressor will turn ON when the bucket is properly installed. Also, check the float valve in the bucket (if yours has one) to make sure it is not stuck in the 'UP' position.

Hope this helped 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.

How do i check if its working correctly


If you want to give it the ultimate in-home test. Put the dehumidifier in the bathroom with the door closed and a hot shower running, but do not turn on the bathroom exhaust fan. Set the dehumidifier's controls as low as possible and let it run for 20 minutes. After 20 minutes, return to the bathroom, turn the shower OFF and check the water collection bucket for water. The unit will probably be running anyway, when you return to the bathroom.

Remember, the lower the setting, the more the unit will run and collect water. Until it either reaches the humidity level you have it set for or the bucket is full and the unit automatically turns OFF

That's the best way to test a dehumidifier at home. Hope it helps you.
Please let me know.

I have purchaced two maytag dehumidifiers M7DH45B2A either one works. I cleaned inside and out blew out the coils with air. Motor runs but will not take out the humidity.


You may have the humidity level set to high. Keep in mind, the higher the number on your LED screen, (if your units have LED display) the more humidity remains in the house. Lowering the numbers on the screen (to 45%), should have a better affect.

Hope this helps you. Please let me know.

Our dehumidifier turns on for only a few seconds, then shuts off.


Wendy, it's probably because the humidity level on the unit is set higher than the humidity level in the house. Keep in mind, the humidity level you set the control to, is not the amount extracted from the air. It's the level you want it to maintain. The higher the percentage level, the more humidity stays in the house. The lower the percentage level, the more humidity it removes, until the lower humidity level is reached. Then the humidifier will automatically shut OFF and/or the unit shuts OFF, because the bucket is full. Once it's emptied and replaced, if the unit needs to continue to extract humidity, it will start running again.

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

My dehumidifier is not working properly. I do not know how it works, I do not have the manual. I have a temperaturesetting and a humidity level area. Do I need to set it on the humidity level to pull water...


Yes set unit humidity dial about half way or until it comes on. You need something to measure humidity. most of dials dont have a humidity reading. Set at about 50% Rus

Check room humidity, if it is already below 35 it will not start because that is the lowest it will work to.
