I'm no genius, but a couple of YouTube videos, the right tools, and 30 minutes was all I needed to do the replacement. Appliancepartspros.com made it easy to find the right part, charged a fair price, and shipped wicked fast. I've used these guys a few times now, and I can also add that they're not great just sometimes; they're consistently great.
You'll need a small selection of screwdrivers and/or a socket set. If you have eyes like mine, you'll probably also need a flashlight. You're about to save yourself $300-$400 by doing this yourself: good luck!
