Less than two years ago, I bought a Whirlpool dehumidifier model
AD50DSS2. This is a 50 pint, manual control unit. I wanted a manual
control type because I built my own controller which wouldn't work with
electronic control dehumidifiers. Note: It is hard to find a manual control
type of dehumidifier, which was common years ago.
I became very disappointed with it because of the vibration noise. The
noise isn't there all the time. I called Whirlpool about the vibration
noise, and they sent a service man. He opened up the unit and checked for
loose components. He put some kind of compound down where the compressor
is located. It seemed to fix the problem at first, but after he left, the
noise was back. I will spare you the details regarding the number of times I
worked on this "infernal machine". Note: I am a consumer products
service technician (repair TVs, etc.). It seems as though the "housing"
(cabinet) resonates with the compressor vibration, thus "amplifying" the
vibration noise. If I squeeze on the sides of the cabinet, the noise goes
down. The degree of vibration noise seems to be dependent on the room
temperature and humidity.
I can't tell you how many times I felt like getting the sledge hammer
and using it to fix the noise permanently, but where would I find a
manual control, 50 pint dehumidifier?
Before this Whirlpool, I had a quiet Goldstar dehumidifier (manual
control) for many years. Eventually the compressor went bad. I was told it
would be too expensive to get it repaired. Unfortunately, I put it out for
trash, and I bought this Whirlpool.
The reason I posted this is to warn you if you are thinking about buying
a dehumidifier, go with another brand.

Since you have built your own controller, what's the big
deal with wiring your controller into an electronic dehum?
All you need to power is the fan, compressor, freeze stat,
and the switch that tells if the bucket is full. The wiring
ought to be easy enough.
Since you have your own controller, you should be able to
make a window AC into a dehum. Some control wiring, and
build a drain under the evaporator.
Never occured to you, to glue some styrofoam insullation to
the sides of the unit? Change the weight of the sheet metal,
and change its resonant frequency.
I went throught this recently with a Sears/LG unit. Whatever was
making it vibrate was inacessible. I finally realized that placing
some weight on top of it completely solved it. Now I have a case of
bottled water sitting on it. It was also sensitive to the type of
weight. Stacking metal weights just as heavy did very little. I
think the water probably helps absorb the resonance.
