This has 4 seperate switches to activate the spark modue, the chances they have all failed at once is remote.
More likely to be a bad spark generaor. Its also possible that the wiring is damaged.
Once you have the hob out, and the screws removed, the glass top should lift off. Remember though it will be stuck after years of use .
