Sometimes an Aria or Yun can fail to a point where replacing the ultrasonic disc just isn't enough. The whole ultrasonic driver circuit can fail and then there's no mist output at all.
This video explains how to replace this part with a custom made driver assembly by DiffuserDoc, LLC. .
This method can also be applied to the YL Bamboo and Rainstone diffusers.
