I am having problem keeping the temp below 300. I had no problems for a long time (the first year I owned my Egg) then I replaced my gasket and the egg always wants to stay around 285 or higher. It passes the dollar bill test and the vents are nearly closed (pics below). The only thing I can think is that I need to clear out the silicon around the draft door and re-caulk since it seems to be degrading and cracking and maybe that is letting air in. Let me know what you think. Thanks for the help in advance!
