Garage Door Opener only closes (Genie Pro)
I have a Genie Pro Screw Driver opener and it stopped opening the garage door yesterday. When I press the wall button it only opens the door one inch and the door stops moving, but the opener still continues to run. If I manually open the garage door and press the wall button, it closes the door fine. Pressing the wall button again will give the same issue (open one inch only).
Does anyone have any idea of what could be wrong?
Thanks a lot!
