Sunbeam humidifier - I have model SUL495 I woke up and it wasn't doing anything. Won't even turn on. What can be wrong?
I would recommend you check for a blocked vibrating membrane. It uses membrane to create pressure waves in the water that are normally released into the water. Check out how to prepare it on http://www.ehow.com/how_4702283_repair-ultrasonic-humidifier.html.
