Here is a better wiring diagram
I am assuming the stove top elements are OK.
If not then you may have a house electrical problem.
Check the wiring at the units terminal block.
Check the wiring from the control board to the elements.
Check the temperature probe, should be around 1100 ohms at room temperature.
If all the above are OK then the control board is probably toast.
