Well, I ordered the new part or one that matched close to the one I needed. Replacing the part was easy, and took about 15min. Had to take out the ice tray and the rear panel l to get to the fan, once I did that it was the rest of the way. The old fan had a different way it was connected, but that really wasn't a problem. All I know that it works great and I can lower the temp and it is just as cold or colder than before.
