Table of Contents
This gas range uses two Carborundum igni-
tors to provide a source for igniting gas from
the bake and broil burners. Norton ignitors
were previously used in the Whirlpool gas
ranges, and both of these ignitors operate the
same way. The only differences are in the
design (see the illustrations), and in the cur-
rent ratings.
Carborundum Ignitor
2.5 - 3.0 Amps
The oven ignitor system in these Whirlpool
gas ranges has the following three main com-
ponents, and is wired in a series-parallel cir-
cuit (see the illustration below):
1. An Electronic Oven Control (EOC).
2. Two Carborundum Ignitors (Bake &
Broil).
3. Dual Gas Safety Valve.

A Carborundum ignitor uses a round design,
and limits the operating current flow to be-
tween 2.5 and 3.0 amperes.
A Norton ignitor uses a rectangular design,
and limits the operating current flow to be-
tween 3.2 and 3.6 amperes.
All of the self-clean gas ranges use these
components. When the EOC is set to the bake
or broil mode and a temperature is selected,
the relay on the EOC closes, and provides
power to the ignitor. With power applied, cur-
rent flows through the ignitor circuit, and the
ignitor begins to heat and glow.
