I have a Hamilton Beach 52 inch ceiling fan which I installed at least 10 years ago. I need to take it down but cannot figure out how to unlock the canopy cover to remove the canopy. I believe the fan # is 0001577.

Can anyone help?

I'm sorry - this is a Hamilton Bay ceiling fan. I can't figure out how to edit my original post.

Grab the top ring and twist to left. Should rotate to point where ring will drop down and you can then remove screws.
