garage door drive gear issue
We recently had our Craftsman garage door serviced because it wouldnÃ¯Â¿Â½t open. They had to replace the torsion spring assembly as well as the top brackets on each side. That was about a month ago. Now I came home and the door wouldnÃ¯Â¿Â½t shut. I opened up the lid to the garage door opener and the drive gear was trashed. There were white plastic shavings everywhere. It looks like that was the only part damaged. I was going to just replace it, but wanted to check something. Is it possible that fixing the other parts may have caused this to happen? I donÃ¯Â¿Â½t want to waste time replacing the gear if itÃ¯Â¿Â½s just going to do it again.
