The title kind of says it all. I left two pieces of papers on top of vent holes ( covered the top entirely ) while it's on. I'm wondering if got to point that is too for it so the heat may costed some unknown damages. I'm asking everybody opinions. I love this unit dearly I'm feeling so bad.
Thanks for your reply. It was running like that for about three hours. I did not see any smoke or smell anything but I think it was hotter than normal. OK I can smell something but it might be a breaking in smell. I just bought it new and used a few times.
