I have an old Lynx overhead door opener controlling a double width
wood garage door.
When left to close on its own, at about the half-closed point, it
stops and opens, as if it has hit something. I can force it to close
by "helping" the door down with my hand.
Is there a friction trip adjustment on the unit that will allow me to
decrease the sensitivity? Or might my problem be work rollers on the
tracks? I have lubed the rollers, but they are old.
Any suggestions appreciated.
