Very loud vibration when the fan runs.

a change in tone of the noise from a working unit indicates to me that a bit of dust/dirt has built up on the internal fans blades and has caused a imbalance in the fan now , this usually requires a complete disassembly and cleaning out to remedy

vibrations are from unbalanced item
check for dirt build up on the fan blades

It may not be setting on a level floor or the hardwood flooring or tile flooring is allowing it to vibrate more than it normally should. Also, remove the air intake filter to make sure it's clean.

Hope this helped you, Kathy. Please let me know. Thanks.

Hi,
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

Dehumidifier is running but no water is in bucket

It sounds like the bearings in the motor are worn out, especially as you said it quits running at times. You should be safe in just replacing the fan motor, but check the fan blade to make sure it isn't out of balance for any reason(dirty, missing a balance weight, or bent). Hope I was of assistence!

Well to knowledge the problem 40 percent is dry. means your basement is great. humidity should be 30/50 percent 50 grows mold. also if it runs for a min the auot shut off is activating. check this first.

I thnk you are expecting too much from your machine. DO NOT RUN IT WHEN IT IS FROZEN!

This is what I would do. Slow down the process. You shuld be agle to select the % humidity you seek. Set it high, say 90. Get another fan in your basement working to sirculate the air. When your machine has achieved this goal without excessive running and freezing, go to 85% or 80%. It may help if you direct a small fan at the coil that freezes.

Are you certain your machine drains properly? Hose to a sump pump? Is the sump pumping properly?

And lastly, you may want to add a second machine. I operate two in my basement and they keep it 50% in the summer. My basement is about 4000 cubic feet.

I hope this helps you

did you try to open the unit, unplug it of cause..something may have entered the unit fan.
you may have to physically remove said object.

Your coil temperature has to be below the dewpoint of the air in the basement to remove the moisture. If you can set the temperature lower or the fan speed lower it will help.

A Dehumidifier will not cool your basement, just make it seem cooler at the same temp. Your dehumidifier may be undersized even for that purpose.

You need an AC outlet of a central AC in your basement, or a window unit if there are windows.

Warm air at discharge is normal.
