Product review (4 stars): It's a knob
This part number is what our range manual listed as our replacement part.  However, even adjusted as far as possible, our thermostat is still about 25 degrees off.  Easy to remedy, as long as I remember.  I just set the oven to 400 instead of 425, and use a rack thermometer to check if it needs adjusting once it is preheated, before baking.
