Product review (5 stars): so hopefully this one will not crack like the originals
I used this to replace the gray original knobs on my GE dryer and it worked perfectly. The slot is reinforced to be much thicker than the previous knobs, so hopefully this one will not crack like the originals. The selector line on the knob runs parallel with the straight line of the "D" shaped slot, vs some other knobs on Amazon being perpendicular.
