Thank you for your help Robert,
I called mcapplience which is the manufacturer of the fridge and they have the cord Jake suggested but told me it won't fit. But I wonder why both Jake and Sears thought it will. May be I should buy it in Sears and just try, they do look similar.
After I learned how you came up with that part # I went to mcapplience.com and checked it. I found out that you can search only separately by model number or the name or number of the part. If you enter the model number it gives you parts in alphabetical order and the power cord part # is 3050100117, it is on back order. if you enter model number and the part name together it gives you several power cords none of which are the right ones. I did call them today again and they confirmed that it happens because of the wrong way of searching
