I recently installed a Chamberlain 1/2 hp belt drive opener. About 9 times out of 10 when the door is closing the rail "jumps up" where the trolly is at (approx 1' from the end) and the door reverses and goes back up? Somenting is getting in a bind at that point but I cannot figure out what it is. The door moves easily and free when not attached to the opener.
