garage door damage
What they said, the door tried to close on something that damaged it. But..........there are adjustments that are supposed to allow the door to lightly touch an obstacle and then reverse direction. I say lightly, because it is intended to reverse without damaging a human body or part. The adjustment has to be way out or there has to be a malfunction for the door to close hard enough to damage parts. So either the way the opener is at fault, by the installer not making proper adjustments, or due to a malfunction.
I am assuming there was no damage to the car???
