First I unplugged the unit. I used a screwdriver to pry the damper cover insert off and then removed the two screws from the larger cover. I then just pulled the piece of foam off. If you unclip one of the upper clips then you can pull the damper out and disconnect the cable assembly. Then you just plug the new cable in and slide it back in. You can easily test it by leaving the door open and letting the damper open up.
