Whirlpool DE47-00006A Microwave Light Socket OEM Part

I found the information (appliance serial nu.) on the side of the open micro wave door along with the may tag web site that I needed to use. When I went on site the first thing that was ask was what appliance was I interest in, A list of may tag appliance appeared and I chose the one I needed. Then I was ask for the app.serial nu.. A picture of the microwave that I have appeared and I type what I needed (light bulb fixture). another picture appeared and I check to make sure it was the right one.I also found a short video on the part that I was replacing that came in handy too. I'm a little nervous when it comes to electric.All in all the site and video made it real easy to fix it my self instead of calling a repair man and being charged for service.The part I replace had a crack in it. That was the problem. Thanks for the help.
