Question about Sunbeam 699 Humidifier
The Problem is minerals in the water. Impeller and ultrasonic designs send these minerals into the air. If the water in your area contains a lot of minerals, you will notice them as dust. The EPA does not issue health warnings about minerals in the air, but does recommend using low-mineral water (such as distilled water) in your humidifier. Many ultrasonic models feature a demineralization cartridge that filters minerals out of the water to prevent the dust.

sounds like the small fan that is located in the base isn`t pushing the mist out. unplug it then take all the screws out of the base. there are screws under the black foam stands too. be careful not to touch anything that looks like live wires while you look inside then look inside while it is pluged in. it should turn. check for something blocking it like lint or dirt..you may be able to clean around the shaft with w d 40

It sounds very much like the transducer has failed. This is likely a crystal transducer and since they produce the agitation that should cause a mist, they are running continuously; not a good thing for something that is trying to shake iteslf apart all the time.
These require input from a circuit that produces the fairly high level of power needed to drive the crystal so it could also be the source of the problem.
This isn't something an owner is able to diagnose unless they have some technical training.

tentative on the Solution icon ...
I picked this up a couple days ago at the Salvation Army, 3 bucks. I also had way too much damp coming out, saturating anything near.
I read through the comments, and one folk said they uncovered the spaz unit and tightened the screw they found there, to no avail. They asked if they should reopen and loosened the screw ...
Which I did. Took me a while, and maybe those who aren't used to investigating the inner workings shouldn't try it unless they're willing to make a mistake and throw it away, but ...
I loosened the screw. Not sure if it was a quarter turn or a half turn; I wanted to do more and have learned many times that "more" is not "better."
I have a cardboard box in front of the unit for hours now, and it is not saturated.
The factory setting, whether it be for all or some, is too wet. Loosening the screw that shows through the computer board has, for me, made the unit more tolerable. Takes an eyeglass-screwdriver to get it done, but if'n ya has the general know-how to investigate things, maybe it'll work for you.
