Hi, my wall button has no power going to it, reset the breakers but power seems to come on sporadically to the unit.
It will come on, I hit the button, the door will go down 3/4 of the way and then go back up and then power goes out again at the wall switch. Any ideas of what this could be
The lights will come on when I manually open the garage door with my hands. It's weird.
Start by checking the wiring. Look for a loose connection, broken wire, or short.
Is anything hanging from the door that could swing into the path of the safety sensors. Clean the lenses.
