Garage door opener sensors: a question of alignment
I have a Sears garage door opener that is about 14 years old. It has worked well over that time but occasionally, the sensors that prevent closure if something is blocking the door get out of alignment and have to be adjusted. I have always been able to do that until now. I have some construction going on in the house and the workmen piled stuff in the garage and knocked the sensors out of kilter. I have tried and tried to realign them without success. Any suggestions for how to do this? Thanks!
