THEORY OF OPERATION

INTRODUCTION

The Direct Spark Ignition System contains a Gas Distribution Valve and a Direct Spark Ig- nition (DSI) Control that interfaces with the Electronic Oven Control, and spark electrodes. This provides the direct spark ignition and gas distribution for Whirlpool self-cleaning gas free- standing ranges.

A proper ground and the correct polarity is nec- essary for the DSI control to sense the pres-

ence of a flame. If the polarity is reversed, or in some cases if there is a poor ground, the control will appear to operate normally. How- ever, after an oven burner ignites, the spark will continue to occur at the burner, and the valve will then shut off after 4 seconds. This is because the DSI control does not recognize the presence of a flame when one is present (see “Monitoring System,” on page 9).
