GE cooktop burner not lighting up

1 of 4 burners will not light up. When control knob is turned, the burner makes a "click-click" sound like it’s igniting, but doesn’t light up. After a week or so, tried again, and it no longer makes the "click-click" sound. Still not lighting up. The other 3 burners continues to work normally. Should I replace ignitor switch or spark module? What’s part#?
