Question about Maytag M7DH45B2A Dehumidifier

1 Answer

Dehumidifier emptys in the floor.

My dehumidifier is probably 5 years old. I have had it repaired once at the local Maytag repair shop. Now it is overflowing in the floor. I do not have it
hooked into a drain. The bucket fills and it doesn't cut off. It remains on and keeps removing water, then continullay overflows unless I remember to go downstairs and empty it. Then I have to put the shop vac hose in the bucket to remove some of the water so that I can empty the bucket. Also **** up all the water in my basement floor. What is the matter? I know that it needs cleaned and the little thingly in the bucket is in place. Can I use a hose into a basement sink? Will it drain if the sink is higher than the dehumidifier? I'll admit I am a little dumb here.
I have a drain in the basement floor but I really don't want to remove the
plug and put a hose in it. Can you advise me?????

Check the float first - be sure the styrofoam on the bottom is still intact.  Be sure that you can move it up and down freely (and easily) with the bucket out of the machine.  If that is not bound up, and the foam is in place, next check the switch in the dehumidifier itself.  It's directly behind where the float goes - the way to test it is to turn the dehumidifier on and push the metal tab in with your finger.  The machine should cut out immediately - if it does not - the microswitch needs to be replaced.  (they're very cheap, and simple to replace)

Hello, We have/had a seven-year old unit which was working fine till a few days ago. First, I noticed a pillow-size pool on our basement floor two consecutive days. I moved round the unit since we thought...


It's 7 years old and has severed you well. Repairs on a unit that old, cold cost as much as a new unit. That's, if the parts are still available for a 7 year old dehumidifier.

As far as advice is concerned ... I agree with you. Since you're using it primarily in a basement. Shop for a low temperature unit. That's one that will function well, between 40 & 60 degrees F. I say this, because the ambient air temperature at floor level in a basement, can be 5 to 8 degrees cooler than the air temperature at chest level. Regular dehumidifiers don't function well at the temperatures I referenced above.

The other features you want to look at is energy efficiency and the square footage or cubic footage it's rated to handle. I would suggest, no matter what you buy, if an extended warranty is available ...buy it. It could be money well spent. Then, only the Routine Maintenance is up to you. Which means, don't misplace your owner's Manual.

Hope this helped you. Please let me know.

How to repair or fix a Dehumidifier when it leaks or overflows


Nine times out of ten, a problem with a dehumidifier can be traced to electrical parts-not to the compressor. If the problem is being caused by the compressor and the unit is out of warranty (most have a 1-year limited warranty), strongly consider replacing the unit rather than trying to have the compressor repaired. If you're thinking about having the unit repaired, be sure to ask for an estimate.

Unless it is designed to drain automatically, a dehumidifier should be emptied fairly often during hot and muggy or damp weather- sometimes as often as once a day. In humid, damp climates, a dehumidifier's reservoir can pull as much as 50 pints of water from the air a day. Failure to keep the reservoir clean and dry will just contribute to the problems you're trying to solve. If you're in the market for a new dehumidifier, consider its reservoir capacity: Larger capacity reservoirs work more efficiently and have to be emptied less often.
Many dehumidifiers have a float switch that prevents the unit from spilling over with the water that has been drawn out of the air. Sometimes this switch goes bad and must be replaced. If your dehumidifier is overflowing, you can test the overflow prevention switch with a volt-ohm meter.
1) Unplug the dehumidifier and remove the switch.
2) Disconnect the leads and clip the leads to the terminals on the switch.
3) Check the pan or reservoir and empty it if necessary, or make sure the drain isn't clogged.
4) Straighten any kinks or bends in the unit's hose.
5) Set a volt-ohm meter to the RX1 scale (or to K-ω or ω resistance on a digital meter) and depress the bar or trip lever on the switch. If the meter's needle shows no continuity as the switch is clicked back and forth, the switch is probably faulty and will need replacement.

My dehumidifier smells like its burning when I turn it on. It is about 5 years old, does this mean I need a new one?


Judy, the fan motor or the compressor motor may be failing. It's cheaper and less of a hassle, to replace a 5 year old unit, than it is to repair it.

Hope this helped you.

If your dehumidifier doesn't seem to run often but the humidity in the room is high, try adjusting the humidistat control on the dehumidifier to a dryer setting. If the dehumidifier seems to run constantly, but there's little or no water in the container, there may be a problem in the refrigeration system. Try cleaning the unit. If that doesn't work, you can't repair the refrigeration system yourself, you need a qualified appliance repair technician to do that.

I have a dehumidifier that runs but does not pull moisture from the air in the basement. the application is about 3-5 years old. It is a Maytag and I purchased it at Home Depot. The Model is M3DG30B2A A....


There are a couple of things you can check for and they are; First of all, when you say the unit is running you may only be hearing the fan run. The compressor may possibly be not running(if it isn't running you will have no dehumidification as a dehumidifier is really nothing more than a small airconditioner.(cooling a coil for the moisture in the space to condense to). Second, The space may be to cool for the unit to run and dehumidify well, The space should at least be 65 degrees or warmer. Third, the system may have a leak and it is out of or low on refrigerant(freon). Depending on what you paid for the unit and if it has any remaining warranty(parts only-labor not covered) if the system is out of refrigerant or if the compressor is bad it probably isn't worth the cost to repair.

Maytag dehumidifier model m7dh45b2a about 2 years old (5 year warranty) runs but does not remove any water


call 1-866-629-8241. they are no longer honoring the warranty because the company that made the dehumidifier (fedders) went bankrupt. they will prorate the warranty and send you a check. we had two months to go on ours and they sent us a check for $14 and change.
