Question about Maytag M3DH30B2A Dehumidifier

My dehumidifier is squealing

My Maytag dehumidifier runs frequently and from time to time starts squealing. If I smack the casing the squealing stops for a while. Sometimes it stops for a while temporarily.

I'm unsure whether it's a good idea to take the plastic casing off to see whether if there's any way to fix the problem inside.

    Same problem, fixed for a couple of months by adding hi-temp/ hi-pressure grease to the motor bushings. Temporary fix. Squealing returned and then the fan motor stopped working at all although it does spin freely. Suspect humidistat control now? Turning the control to run-full-time does not work, either. Light does come on so unit has power. Heard there was a recall on these units from someone who bought the product at BJ's. Any ideas?

The fan motor is the cause it needs to be replaced

It is loud vibrating when comp. runs if I tip the unit up 3or4 inches it stops vibating is this ok too run this way?


No, not really. As the unit has to be in a level position to operate properly and not overflow.
If the unit is sitting on carpet, this will often times cause the vibration noise. I don't know why, but it does and it does with my 4 year old LG unit. I have noticed, that once the tank reaches the 1/2 full point, it will vibrate sometimes. I solved the problem by firmly smacking the left & right sides of cabinet at the same time, with my open hands. The vibration stops immediately and continues to run until it shuts off because, the humidity extraction level has been reached or the tank is Full & needs to be emptied.

It's a simple solution, but it works. I hope it works for you and thanks for choosing FixYa.

I PURCHASED MY DEHUMIDIFIER CA 2 YRS AGO. ONLY USE IT OCCASIONALLY IN MY GARAGE IN THE SUMMER. RUNS FINE, BUT DOES NOT COLLECT ANY MOISTURE IN THE BUCKET. WHAT COULD BE THE PROBLEM? Thanks


check to make sure the compressor is running. try smacking it 5/6 times with a hammer while it's running, surrounding lights should dim for a second, should have low hum sound. This solved my problem

My dehumidifer collect water but the fan blows hot her so it makes the room hotter


This may be caused by running the unit in continuous mode, rather than timed mode. The heat is generally is generated when the defrost mode cycles on, to defrost the cooling coils. This happens more frequently, if the air space around the unit is obstructed or it's operating in a temperature range of 40 to 60 F. Cleaning the air intake filter at least once a week, can help solve this problem, too.

Maintain a minimum of 12" free air space around all sides of the dehumidifier. Use a timed mode rather than a continuous mode. Make sure the room is within the proper operating temperature range and clean the air intake filter weekly.

Hope this helped you troubleshoot and solve the problem.

Hi,

This one has a leak in the refrigerant system... it will need to be found, fixed, and recharged...which will cost more then a new one...in most cases.

Hello :) There is a tube that is hanging out of the back of the dehumidifier... so I need this to operate it? Can I use without it?


is there an internal storage tank for that unit. It is probably the drain tube for condensate. Put it into a bucket, run it, and see it water accumulates. If so, that's what it is, and must be put into a bucket, that then must be emptied frequently.

Maytag dehumidifier runs all the time


if your dehumidifier is under warranty, call 1-866-629-8241. they are no longer honoring the warranties, because fedders, the company that made the dehumidifiers went bankrupt. but they will prorate your warranty and send you a check. we had two months to go on our warranty and they gave us $14 and change back.
