This is tonia again, if the front knob still works the bridge element, just not the left front burner, does that mean the problem is the burner and not the switch?
Answer Hello Tonia. You will need to test the burner and see if it is bad. See if the switch is sending power to the burner. If so, and the burner does not work replace the burner 318258201. If there is no power, replace the switch 318191023. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter.

Is this the right part? We have 3 burners out on our ceramic cooktop so need to replace all three (went out at different times).
Answer Hello KC! It would depend on which burner you would be. It seems there are three different sized burners on your model. The left and right rear is part number 318198817. The right front is part number 318198925. The left front is part number 318198819. Thanks!
