If the door closes and then opens again on its own, adjust the rod in the tube to provide 1 inch of cushion compression when the door is completely closed. Adjust one-fourth turn to 1 inch of travel, counterclockwise for the open limit and clockwise for the close limit. If the door doesn't open and close properly, adjust the limit with a screwdriver. If there's a buildup of snow and ice, clear the area. You can disconnect the door from the remote operator, and open the door by hand.
If the door doesn't open and the light flashes, make sure there's nothing obstructing the door.
Also check the wires by disconnecting the wires at the opener from the wall station. If your Wayne Dalton Garage Door Opener doesn't seem to be working right, make sure all the batteries are up to date, and the cord, outlet and wall switch work properly.
