The model number of the cook top is JGP933SEJ1SS. The main problem is that the burner head could not fully cover the base. It was out of shape and looked like a small dome. After ordering the burner head WB16T10030, I discovered that it did not match the existing burner base. After some research, I decided to order this newer base WB16T10029.
The replacement of the burner base does take a little effort mainly because it was not clear how I should pull out the igniter which was holding the base. I was able to found a video that showed me to use a flat head screwdriver to separate it from the cooktop. Then I just needed to carefully pull the wire from the igniter. Again it took some time for me to insert the wire back correctly to ensure inner wire was making contact with the igniter. After everything was put back together, the flame looked blue and nice.
