Question about Maytag M7DH65B2A Dehumidifier

3 Answers

Dehumidifier doesn't turn on at all.

My dehumidifier won't turn on at all. I'm assuming it is a fuse. It has a clean filter and good power running to it. What things can I check or replace to get it up and running again?

This dehumidiifier has an inherent design problem. There is a control printed-circuit board mounted above the cold coil, sitting in a shallow plastic well. The moist air eventuall condenses in the well and shorts out the board. I have found this on 2 units now. You can order a new board on line and it installs with just push on wire connectors. That will fix the unit but I suggest you mount the new board with longer screws and spacers to raise it out of the well.

Jeffs answer is right on. I purchased a new circuit board for $33.00 and installed it with some plastic washers as spacers and the unit started right up. You could see the black marks on the back side of the circuit board where it shorted out.
Thanks for the help.

Unplug then replug. I think the electronics get "confused" sometimes.

My dehumidifier continually runs and removes little water. I cleaned the front filter and the manual says to clean the back filter but I can't get to the back filter. How can I reach it to clean it?

Makes a loud beep every minute or so. Doesn't seem like basket is filling with water either.


Turn the Master ON/Off Switch to OFF and unplug the unit. Remove the air intake filter and clean it. Allow it to thoroughly dry, before reinstalling it. Once the filter is thoroughly dry, reinstall it, plug the unit back in and turn the Master ON/OFF Switch to ON. Set the humidity level at 35% and allow the unit to run as you normally would. The beating should have stopped, since you cleaned the filter. Be sure to maintain at least 2 feet of clear air space around the dehumidifier.

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

Dehumdifier not collecting water.


It may be that the humidity level or temperature in the room where your dehumidifier is located is too low.

When the outdoor temperature is below 50 F, the indoor air will be dry even when the air inside is warm, therefore when it's cold outside the dehumidifier may collect little or no water.

Air conditioners will also remove moisture from the room, even if it's hot and humid outside, resulting in little or no moisture collecting in the dehumidifier bucket.

Some dehumidifiers have a deicer which turns off the compressor but keeps the fan running. When the compressor is off, moisture is not removed from the air. The deicer turns off the compressor when the room temperature is cold.

Some dehumidifiers do not have a deicer. If the room temperature is low enough, ice may form on the evaporator coil. The ice prevents the dehumidifier from removing and collecting water. If ice forms on coils, unplug dehumidifier until ice melts and room temperature rises.

The filter (on some models) may be dirty or clogged. If so, clean the filter. For instructions on cleaning the filter.

I hope this help to solve, if this answer solve it, remember to rate it. Good luck.

Water is not going into the tank, but it does run and panel lights up. Filter is clean. It worked for the past 2 months.


Hi,

First, make sure the humidistat isn't set too high by adjusting it to the lowest humidity setting and running it again.

Next, test the dehumidifier by placing it in a closed bathroom with a hot shower running.

If you don't see water collecting in the unit after several minutes, turn the unit off and clean all dehumidifier filters and coils.

If, after adjusting the settings and cleaning the unit, you still don't see water collecting, you may have a refrigeration issue. This situation will have to be addressed by a qualified technician.

Good luck
