One thing I have a question about. I ordered the kit from Geno's. The cover fits however the latches on the sides to not click or secure to anything. It feels like it just sits there. The filter is pushed in as far as it can possibly go and the cover seems to ride on it almost. I tried different things but ultimately, even when pushed solidly against the ductwork, the cover does not latch on.
It is the right cover, it is just snug. One side of mine did that but after pushing for a minute I got the other side to click in. It's just very tight. Try getting one side snapped first.
