ELECTRONIC IGNITION SYSTEM

OPERATION

The Electronic Ignition System performs the same function as the standing pilot ignition system. However, instead of using a standing pilot flame to ignite the main burners, a spark from a surface burner ignitor is used.

The electronic ignition system consists of the following components:

1.Ignitor Switches

2.Ignitor Spark Module

3.Surface Burner Ignitors (electrodes)

Ignitor Switches control the voltage to the ignitor spark module by opening and closing the circuit. The ignitor switches are mounted on the stem of each burner control valve, and are rotary-actuated. There are two types of switches used on Whirlpool ranges. One is for a 90˚ valve, shown in Figure 3-29, and the other is for a 220˚ valve. Each gas valve has its own ignitor switch. The ignitor switches are wired in parallel.
