Burner Problems for Kenmore 790.99123404 Range - Middle of this 3-section element is acting strangely

[whitedavidp]

Hello. Many years ago I had to have the 3-section, right front element replaced. And this morning it seems to be acting strangely again. This time, it seems that the middle section is hesitant to heat up. If I more the tea kettle that was on it around into various positions and turned the whole element off/on and such, it did seem to light up at least for a while. But the intensity seemed somehow lower when it did light up. Any suggestions? Thanks

There are 2 parts involved, the element itself which has 3 section and the surface unit control board.  Need to get access to somewhere to get voltage readings. Think the element would be the best choice.
