First, turn off the power to the stove. To test the switches remove the wires and test for continuity, they should only have continuity at the point where LITE is on the knob. So when you turn the knob to the LITE position, as if you were starting the burner, the switch should have continuity.
Check for any burnt or loose wires (bad grounds) of course. Make sure the tips of the igniters are clean and the spot on the burner where it arcs to must also be clean.
If the switches, wires and igniters check out then check out the module. If the spark module is getting power and you turn the knob to LITE it should send the spark to the igniter. If not the replacing the module may be be in order.
