Garage door not working sear craftsman 1/3 hp
I just got a new house and this garage door is old as dirt. I think it from 1992. The motor doesn't look to be turning the chain at all. Should i just replace the operator or is there more to it? I know nothing about these things and was wondering if i got a new one if it would even work with the parts that are up there now. Any help is appreciated!
