Tight hinge side
What you will need to do is as follows.
Firstly apply talc or baby powder to the hinge side of the seal, and also to the area on the fridge that the seal will hit on the hinge side.
Then as you are closing the door, gently put a flat screwdriver or similar(butter knife etc, something not sharp) between the seal and the actual unit.
You will need to make the entire side flat, so that it is not twisting at all.
Then leave the door shut for a couple of hours, and it will mold into the flattened state.
Unfortunately Westinghouse seals are always a bit tight, and this is the way to rectify the problem.
