You all crack me up with your comments.
I figured it out.
Yesterday, shortly after the "boom" we opened the garage door. It got stuck half way...hit it again, and it went all the way up.....didn't think much about it. Today, it got stuck again. This time we noticed that the coil spring on the garage door had sprung. BOOM!!!! oh well, now we know. Just so you all know, it's very loud when that happens!😱
