Product review (4 stars): Cook top knob fits, a bit high
We got this as a replacement for a knob that melted. There was no exact match for the part number and this was the closest. It goes onto the stem, but seems to sit a bit higher than the other knobs. Still, it does turn on the stem properly, so it's a workable solution. We received it quickly enough, too.

Be aware that these knobs are plastic with a bit of silver/chrome colored trim on the top to make them look classy, just like the original that melted through the trim.
