The transducer disk is on the bottom of the smaller discharge section, about 1/4" in diameter suspended in a rubber ring about 3/8" in diameter.
You can't remove it, but you can soak it and clean it up.

Thanks!
 I looked at mine, and it does look kinda cruddy so will clean it via soaking.


Sometimes the water will cavitate and create a bubble on the disk preventing a mist from forming..usually sucking on the discharge tube will make enough of a vacuum to de-cavitate the water...sometimes less water will get things going [remove reservoir and tip a little water out]

I've had that happen a couple of times when the water level in the small chamber got too high, and removing some of the water did fix that.
