Hi, Am a new user to this forum but I've known about this site for many years I own a volcano and I just noticed this strange thing sometimes happens when the heating element switches on. Basically, there is a short buzzing sound (that sort of sounds like sparks) and a blueish/green light flickering on the inside. It is easier to see in the video than to read my description lol. ^watch with sound on Does this happen to yours? or does this thing need to get sent in?
