When electricity flows to the HSI, the igniter expands slightly, and
amps flow to the dual safety valve. When the bi-metal arm inside the
valve is heated, the arm flexes, opening the valve and allowing gas to
flow to the burner. When operating as expected, the burner should
ignite within a maximum of 90 seconds from the time power is first
supplied to the igniter.
If the igniter glows, but burner does not light, or if the oven is not
heating sufficiently (too cool), the igniter may be too weak and may
not be getting hot enough to open the safety valve as expected.
If gas is flowing as expected to one burner (bake or broil) but not the
other, the igniter is most likely the culprit.
If the igniter or the safety valve are suspected to be faulty, remove
and check for continuity. If no continuity, replace the part. Otherwise,
check the control module for a faulty relay.
