Garage door opener
#1

I have a sear garage door and opener. THe door will not close on down travel. I have adjusted down travel, and checked the sensors to make sure there is nothing in the path. I have diconnected the door from opener and closed the door and re-attached the opener, still no luck, I have greased the track and checked all the rollers. I have diconected power for a couple of days. Once this worked and the door worked find for a while.
Help.
