I called Appliance Parts Pros and gave them the model number of my refrigerator. They promptly advised me exactly what part I needed, told me the price and cost of shipping. I agreed and received my part within 2 days.
I watched the video that told me exactly how to complete repair. It was very simple. The only thing different was that there was a metal strip holding the gasket in place. Removing it was no problem. When I installed it I had to loosen the screws? nuts? slip the gasket underneath and tighten them again. Virtually a piece of cake.
Thanks Appliance Parts Pros!
