Want to replace a ceiling fan which has a remote control. I unscrewed the
three (on this model, there are only three) screws at the top of the
canopy. It twists an inch to each side, but won't come down. It looks like
the metal inside the screw holes (what the canopy screws into) is also
moving. How can I get it unstuck? Twisting over and over isn't helping.

"on this model"

What model is that?

I bet money if you use the make / model, there is a very good chance
of finding the install instructions on this thing called the
Internet.

Reverse to procedure for attaching the canopy.

YMMV
