My mom was washing the light fixture on the ceiling fan when the fixture fall half way down to the floor.How do I put the fixture back up to the proper level? I had an old model in the 80's that I just Yanked on it and it went back up, I don't think I can Yank on this glass and brass model without breaking it... Please help!

We would probably need a picture of this fixture to be able to help. Maybe just treat it like a new installation and redo all steps. How To Install A Ceiling Light Fixture (Electrical DIY) (http://www.videojug.com/film/how-to-install-a-ceiling-light-fixture)
