Trusty Vornado Duo stopped running

The blue light on the power indicator comes on, but no movement. If the light is on, could that be the fuse? Before it stopped working it was tweeting a little, slowing down and coming right back up to full speed. It may have been doing that all day, as I leave it running when I’m not in the room — I only noticed it for a while, I kinda thought it was maybe a brownout situation in the neighborhood… before I really thought about it it was just done… still had the blue light though…
