Replacing Whirlpool Element and Switch, infinite

I need to know if there are any tips when working on a Whirlpool cooktop, [FONT=‘Arial’,‘sans-serif’]GJC3034HB1 [/font], replacing the Element, surface 1000/2400w (Part # AP3126216 whirlpool) along with the Switch-inf, (Part # APE672660 whirlpool).

thanks

Kill the power to the oven, and pill it out of the coutertop, and flip it over, and take the screws out around it, and then the bottom will come off, and then it is pretty easy from there. Tom
