We have a harbor breeze fan/light with a light kit in the middle and 2 fans on either side. It isn't online anymore and we can't get the light kit apart to change the bulb. Any idea how to get the light kit apart?

If the light glass doesn't have any screws, thumbscrews, or anything that unscrews at the bottom, then the glass itself rotates and drops out. You may have to apply gentle pressure.

I had the same problem. Do not try to turn the bottom of the light fixture. Turn only the glass. The glass will turn out. Make sure you are on a safe ladder. Grasp the glass and turn counter clockwise, as if you were taking the cap off on an inverted jar. It will turn out. The bulb is a 75W halogen lamp (very small). To replace the glass, line up the dimples on the glass with the "bumps" on the inside of the light kit then turn clockwise as if you were screwing the cap on a inverted jar. You should be all set.

This (more detailed) description is correct.
