Changing light bulb on harbor breeze ceiling fan model # AER52BK5LKRC
I bought a house seven years ago and it had a harbor breeze ceiling fan model #AER52BK5LKRC. The light bulb recently burned out and I can't for the life of me figure out how to change the bulb. The cover has an arrow on it to tell which way to turn it. I finally got it to turn but all it does is turn then when I turn it the other way to tighten it, it will ony turn a little bit before it gets tight. What am I doing wrong... Please help
