Product review (3 stars): Size is off from OEM even though correct part number.
Assuming they gave me the right part number (the sticker on it says its the right part number), its not OEM size. As you can see by the pictures, its almost half an inch longer than OEM. Width is correct, but length isnt. It still kinda slides in ok since width is fine, and since its tough to find the correct size, Ill keep it and use it. Just wish it was the correct size. I did confirm with Whirlpool W10208631 (and W10208631A) is the correct part number for my WMH31017AB1. My OEM is 12 and 15/16 by 5 and 7/8. This one is 13 and 3/8 by 5 and 7/8.
