While removing the old fan (top), I stripped the nut. Initially thought nut was opposite turn based on research. Had to hack/dremel the shaft to removed fan. Initially ordered wrong replacement fan from another vendor. AppliancePartsPros.com support went about and beyond to ensure the correct fan was ordered. Unfortunately, new fan was busted upon arrival. AppliancePartsPros.com promptly addressed the issue assisted with ordering and the rershipment.
