I looked up the part description on PartSelect. I did not find a match by Kenmore model number (I guess it is really old), so I searched by type of part (knob) and other parameters such as size. There were still a couple of hundred hits, but the very first page had the most relevant match, and the excellent graphics made it easy to see the part I wanted. I was a bit concerned that the original part was white plastic, whereas the replacement was black metal, but I went ahead and ordered anyway. I was a bit put off by the prce i.e. a simple knob costing $20+ is a bit of a rip off, but unfortunately, there is no alternative to find an exact replacement part (the alternative is to buy a new washer for $1000+).
Once I ordered, everything went very smoothly. The part arrived very prompty (I ordered on a Sat, and part arrived on Wed) and it took less than 5 minutes to unpack it and twist it on the washer. And now it works great! I am glad it is metal so won't break off (even though aesthetically, it is not as pretty, being black on a white washer).
Overall, excellent experience at PartSelect. They have a great selection of parts, detailed descriptions/graphics/reviews and excellent service.
