Seems to be running again. We had this problem a year or 2 ago with this thing. The sides and back on the inside are supposed to be kept clear, and when they aren't, it can overheat and shut down. Did the same thing I did last time, moved things away from the walls and left it unplugged for a while, and it is now running again. Not sure what might need to be thrown out, however, cause we don't know how long it was actually off.
