Product review (1 stars): This is not a direct replacement for WB03K10242
This is not a direct replacement if what you have is the older plastic knobs.  While it is a more robust knob it does not fit properly.  One problem is the diameter is smaller than the original, creating a noticeable gap between the knob and the skirt.  Another issue is that it sticks out farther than the original.  The final issue is that it does not fit as snug as the original.  The original took some effort to pull off while this one will fall off if you brush against it.

If your original knob is the original plastic knob, I would try to repair it before buying the "replacement".
