Product review (5 stars): GE OEM replacement part fit perfectly
General Electric WR24X446 Refrigerator Door seal is OEM replacement and fit perfectly.  Laid the seal out flat like they recommended for 1 day before installing. It was packed very well and didn't have any kinks. It was folded nicely with loops, not folds. Some people suggest soaking the seal in a hot bathtub of water, or put it in the dryer for 5 min. or so. I didn't need to.
Removed door, laid flat and removed the old seal by prying up with a putty knife or a screwdriver. Don't pry down hard and damage the edge of the door. Cleaned the groove with a brass toothbrush (it had a little rust on the bottom). Spread a little dish soap on the back of the seal to help it slide in the groove on the door. Best to start in a corner. Work your way around and press hard to snap it in. Tap lightly with a rubber mallet if necessary. You can feel it snap into the groove. Check by grabbing the seal and pulling up. It should be trapped in the groove. Especially check the corners. Make sure they are snapped in and the corner is exactly on the corner of the groove. You can snap in two corners, then press in the seal in between, that way it won't be over stretched in between in case you were pulling on the rubber as you put it in. Clean the mating surface on the refrigerator then re-hang the door. I sprayed some silicone spray on a rag and wiped some on the seal and mating surface. Close the door and check for gaps all the way around. If there is a gap, heat it with a hair dryer until the rubber is soft enough to let the magnet in the seal stick to the refrigerator edge.
