I'm having a problem with my bottom vent and screen. From the get go, it has been tight. I expected this so as prevent air leaks etc.. But it has gotten worse. Tonight I got home and fire it up (XL if that makes any difference). The screen wants to stick and slide with the door and the door moves a lot or nothing. There is no fine tuning temp with the bottom vent because it either slides almost all the way or plumb closed with really nothing in between. Fought so much with it that I was afraid I was going to break the damned thing.
You guys have any ideas? Thanks.
