I knew replacing the heating element wouldn't be a difficult fix, but in looking at the diagram on the AppliancePartsPros.com website, I mis-read the diagram and ordered the wrong element. When it arrived, I realized my mistake and reordered the correct part, while contacting AppliancePartsPros.com of my mistake and requesting authorization to return the item I ordered incorrectly. The new part arrived a day or so later, and installation took all of five minutes.
My experience with AppliancePartsPros was excellent!
