Craftsman GDO Stops Mid Way - Won't Open/Close
I installed a new Craftsman GDO #139.53918D 3 months ago.
For the last 3 weeks, the door has been stopping mid way up or down.
I have reprogrammed each remote and wall unit, but the door only works a few times before stopping mid way again. After the door stops, the remotes will not work for several hours.
I called the teh 800 number. They stated that the problem sounds like it is due to the logic board.
They are sending a new one.
Does it sound like the logic board is causing this problem?
Is the board easy to switch out?
Does anyone have instructions on how to do this, and a link to a website?
