Cooktop burner doesn't stay on on low heat setting

Dear helpful repair people,
I have a 14-year-old GE Profile electric cooktop (smooth top). One of the burners cooks fine on med to high temperatures, but when I turn it down to the low heat (to keep a soup warm, for instance), the burner turns off completely. It also appears to not go on at all if I turn it one to a low temperature from the off position.
So, is this likely to be a burner problem or a switch problem? And, on a 14-year-old appliance, if I fix this, is there likely to be another problem soon? Fix or replace?
Thanks for any help!

Most likely the problem is a bad switch for this burner. The switches are different for different burners, so if you need the correct part number then post which burner is bad.

It is unpredictable.

Thanks, Gene.
This is the front, left burner, 8 inches.
And I assume I’m looking for the infinite switch, not the "control element" - both of which are labelled as part 19 on the diagram.
Does it make any sense to replace the switch on the 6/9" burner, which I use almost as much as the 8 inch burner? (If one switch goes, is the next switch likely to go soon, too?)

Thanks again!

All of the switches are infinite and I do not know why GE called some of them "control element". It sounds really strange to me.

These switches are not cheap, so why you have to replace all of them if they still work?
