The Ignitor Spark Module is a solid-state device that is used to provide high voltage for the top burner ignitors (see Figure 3-30). Whenever the ignitor module is energized by one of the ignitor switches, a solid state circuit and pulse transformer within the module electronically increases the constant AC line voltage to periodic high voltage pulses, and sends these pulses to all of the ignitor electrodes at the same time. The pulses will be sent to the ignitors at about 2 pulses (sparks) per second. There are no adjustments that can be made to the module and it is serviced only as an assembly. The system operates at very low amperage (4 milliamps) so that the high voltage pulses, or sparks, present no severe shock hazard.

TO SURFACE BURNER IGNITOR

A Surface Burner Ignitor is a metal rod with a ceramic insulating body that is wired directly to the ignitor spark module. Pulses from the ignitor module cause the ignitor to arc to the ground strap (see Figure 3-31). These pulses, or sparks, light the top burners through the flash tube.

The surface burner ignitors are manual ignitors that spark whenever a burner valve is in the “lite” position. The module will continue to send pulses to the ignitor until the valve is turned to any position other than “lite.”

Since the system operates on high voltage pulses sparking to ground, it is very important that the range be properly grounded, and that chassis ground through the range is continuous.
