Product review (5 stars): Half the cost of Appliance Parts Stores, the exact part I needed for my 8 inch burner
I've had to replace both of these on my Kenmore electric range.  It seems the larger 8 inch burners go bad before the smaller ones.
Its not the burner itself that goes bad, same burner works fine with the new infinite switch.  Saved me lots of money.  I have a 20 year old Oven Range that works great still.
