I found AppliancePartsPros.com and used my model number to begin locating the seal. My number did not match, it lacked one number. I called the tech support person and she explained that the grid behind the seal on the website was in inches and then I realized that it was the right size. The old seal was made out of fiber cloth and the new one is rubber. It fits and it can be cleaned by removing it after using, unlike the original seal. Very satisfied with the customer service and the replacement part.
