Each burner knob controls a different burner.
so each knob also has to be able to fire the spark module
so that when you want fire it will light. To do this a series of switchs are mounted on the stem of each burner valve. They are all wired to the spark module and so what has happened is ONE OF THEM is stuck ON.
What ya must do is remove all of the knobs and the cover to expose these stem switches. You must then do a test. With the stove on and the spark module doing it ticky ticky you must remove a wire from the first burner(You could get shocked so use your own judgement I use rubber handled needle nose pliers) did the ticky ticky stop? no? go to the next one and so forth. till you find the one that is stuck. Then just replace it. These are cheap.
