if it "became whitish" and is not a stain, no way turn it back to black. Sometimes just heat affects flat top ranges, not so much glass ones though. Did you say
" Comet"? That's what did it, and it is not "too much" it is any at all. Do not use abrasives on glass tops, scratches um all up. Glass cleaner, white vinegar, baking soda for "Scrubbin" and nylon scrubbers , there are non-abrasive cleaners, or at least less abrasive, Bar Keepers Friend, Zuds, do they still make Bon-Ami?. but be careful with them too. Products specifically for glass tops, which don't work any better than any other commercial or homade glass cleaner.
You can buy a new top, now that you know how to open it, even change color. is it worth it? Up to you, how much does whitish bother you? I dunno price of new top, but if you have to order new element or control, you might save on shipping.
Be careful pokin around in there with that meter, 240 volts. Turn the breaker off.. You check the elements with ohm meter with power off, and pwer leads disconnected, not with voltage meter and power on! Jeeze! It'll grab hold of you and if it lets go it'll throw you across the room. If element was good and getting power you wouldn't need to check it for voltage. if ohm meter reads infinity, element is shot. You can check the control with ohm meter, disconnect its leads, mite wanta make drawing or take picture if more than two wires, maybe even if just two. Connect meter turn knob to diff settings. Now you can check voltage. I like to use alligator clips. No, that's as far as I wanna go. I bet the element is burned through any way. I don't want you messin with 240 volts uness we got too. I don'tlike messin with it unless I got to. I was once struck by lightning , in the right big toe, s'truth, so help me. So I am extra careful around lectrical stuff.
