I have a harbor breeze 52 inch avian ceiling fan (model L05BN). I need to remove the glass light cover to replace the bulb. I'm turning the cover counterclockwise and it doesn't come off. I don't see any threads - I don't see any grooves. It just spins. How do I get this thing off?

The whole light assembly removes, not just the globe. 3 screws. Google " avian ceiling fan bulb replacement.". Plenty of hits.
