The lifting linkage attachment tabs broke on my Fantastic Fan vent lid and I was able to secure it in the down position by drilling holes in what was left of the tabs and using some zip ties to hold the lid tight to the fan frame. It’s been working but I’d like to install the replacement lid that finally arrived. It looks like there is some kind of sealant between the hinge and plastic fan frame. I figure that a putty knife with some light tapping should free it up but I don’t want to break anything in the process. I’m leaving on a trip soon and don’t want any major roof problems right now. It seems like a pretty simple task and I’m hoping that someone who has done it can give some guidance. Thanks!
