    Wife wants a new bathroom exhaust fan and I can't figure out how the housing is anchored. There are no screws to back out. I think it was installed, then the ceiling dry wall hung. Any suggestions? I'd be happy with just a cleaning and a new motor. The wife wants me to ask about a complete replace. Thanks, John

    Can you access that area from the attic?

    Maybe for now, you could shove a cellphone camera into the gap (if that black area is a gap and not black insulation) for a clue.

    Most likely there are support brackets at the top of it that screw into the ceiling joists. If you need to do it entirely from that side, meaning you don't have access from above, then you will need to carefully cut it into pieces without damaging the wire and the attached duct. I think an oscillating multi-tool fitted with a metal cutting blade would work well.

    Many do install directly to the framing and the wallboard is applied over the flange. Often, the replacement units are not the same size as the original, so it will require a repair to the finished ceiling regardless.

    If you still have the other parts (motor and vented cover) look for a model number or manufacturer, might be able to google the install manual. That will help you know where it’s attached, and as posted above you’ll have to break/cut in in pieces. Also, try to determine where framing (joist or truss) is located by poking with a skinny screwdriver or putty knife, in the gap between the housing and finished drywall.

    No attic. Flat roof. Since the housing is in useable condition I'll clean it up and go with a new motor and cover. The old motor is really gross. Thanks all.

    Panasonic makes a nice retrofit fan if you decide to remove the housing. But, like others said, most of them are installed before the drywall.
