The close-limitВ switch is a safety measure that keeps people from being hit and having the door close on them-it is a necessary and required device for all garage door openers. If the close-limit switch is set wrong, it may prevent the door from closing It can also cause the opener to reverse or pull back up when you attempt to close it.
