To replace your seal you'll have to remove the screws around the perimeter of the door's inner panel. Once all the screws are off separate the inner panel from the old seal and peel the seal away. It should peel away easily- if not use a Putty Knife to remove it.
Now take your new seal and "soften" it up a little by placing it in hot water for 10 minutes or so. It'll make it easier to place back in the correct position around the door since the seal was probably all twisted up and sharply folded doing shipping/storage.
Now simply lay it back in the same position the old seal was making sure there are no folds, creases or cuts in the seal. It must lay flat or it will leak all over again. Note: there is a sealant that you may want to get that's specially made for these seals to guaranty the seal gaps are filled and the seal stays in place. I use "Kitchen and Tub" Caulk when I don't have any refrigerator caulk available.
Now reassemble the door inner panel, your new seal, and the outer door all together with the screws you previously removed and you're all done.
