I am in a rental with a Comfortmaker RPJ II ac/furnace and I took the covers off to look at the filter yesterday. Coincidence or not, today I have wet carpet outside the louvered closet that houses it. I'm concerned that I may have switched the doors and am creating this issue but I can't find a picture to guide me.

The bottom has the filter and other thing and the top has the inline fan. Would the louvers go on the top and the flat panel with the 'flash viewer' window in the bottom, or just the opposite? I can't see where the water is coming from; inside the closet is the drain and there's dampness, but not enough to be flowing out into the carpet. First concern though, did I switch the doors and can that be a real problem? Thanks!
