Craftsman Garage Door Opener
I have a 2-1/2 HP Craftsman garage door opener with door sensors. The door opener used to work fine when I first installed it. Several weeks ago, I bumped one of the sensors with a board and the door opener hasn't worked properly since using either the remotes or the button inside the garage.
The problem is that when I attempt to close the door with the remote or the inside button, the opener bumps ever so slightly and the opener light flashes a few times. The door will close using the inside button by pressing and holding it down until the door closes. The door will open with the remotes and by pressing and releasing the inside button.
I can't recall whether the light on each sensor should burn bright and can't tell if they are burning at all. Surely, I should be able to see the sensor light.
Any thoughts on how to get the door opener to close using the remote and the inside button without having to hold the button down to close the door.
