Kitchen aid cooktop dual burner problem

Oven/Range/Cooktop Repair
1

I have a Kitchen Aid electric cooktop Model kecc562gbl2. The left front dual burner is not working properly. When it is turned on, both burners come on regardless of which setting is used and the thermostat control does not work properly. Low is like medium and medium is like high. Am I guessing right that it is the infinite switch? With the cost of the switch and the burner element, I’d like to be sure before I order any parts. I’m pretty confident I can replace the parts on my own, but if there is something special I should do when replacing them, please advise. Thank you for your help!

You could check the element with a meter (see the wiring diagram) but it does sound like a control problem.
