Cooktop switch or element

My triple burner will not heat. The power light turns on but none of the single, dual, triple parts of the switch produce any response in the element. I am thinking my problem is the switch unless there is no power to the switch. Am I correct? Could there be a fuse before the switch? Is there any way to get to the switch without totally removing the cooktop? I appreciate any help you can lend.
