Nathaniel for Model Number JMS27G0J3 I ordered a knob for the burner on June 24, 2021. I received it on June 27, 2021. The problem is that the new knob doesn't have the plastic insert which should be attached inside. My old knob has the plastic insert which attaches to the stem in order to turn the burner on. I would like the correct knob shipped to me as soon as possible, along with instructions on how to return the one you sent. Thank you for your prompt attention to this matter, Nathaniel
