Ive done some volt testing and there is 120 volts at each prong where the glass cooktop inserts
You measuring to ground? Should measure accross the pins and get 220-240 volts AC.
and they have been turning on intermittently anywhere from full power to just warm
The elements?...by themselves?
two red pilot lights are also acting funny, off/on/dim, as a matter of fact one of them is completely out, could that make the whole countertop go screwy?
Nope the pilot light shouldn't mess up other things.
I have seen where one of the surface switch contacts welds closed and that has effected other elements....not comming on fully, low or warm only.
Something loose/burnt in the mian power could/would/should effect everything at once.
