Hi all, my first post here....been poking around, looks like alot of good information here...been having a problem with my garage door.
i recently purchased a house, and have a problem with my garage door opener. it goes up without a problem, but going down, you have to hold the button on the wall ,(i have no remotes). i noticed the other day that the bottom wires on the "red" sensor were broken off., i reconnected them, using the other door as a guide, .and still have the same problem. the red light does not light up. how do i tell if i have a bad sensor?
i am not sure of the exact model, but it says intellicode, and i believe my garage is less than 10 years old.
thanks.
