I have a glass top Maytag (I believe the Model is MER6770) that the front right burner at time will stay on high regardless of the setting it is on. Very erratic and you never know when it will suddenly stay on high - there has been a few burnt grilled cheeses. Very difficult to research online, but the best lead I have is that there is an element with a limiter under there that may need to be replaced. Any help here?
Here are your parts

I would say that it is more likely to be the control (infinite) switch.
Either Item 5 or 6 in Section 2.
Not sure which one, it depends on the element type.
Since it is an intermittment problem, is there a way to test the switch?
