Ring Light Removal
There is a ring light under the control panel glass which
is mounted to each burner valve switch. When the con-
trol knob is turned on, the entire ring light will illuminate
the wording highlighted in the red portion of the control
panel glass. To remove the ring light you will need to
follow the preliminary steps listed at the beginning of
this section first. Next, extract the Phillips head screw
that secures the ring light to the valve switch. Lift the
ring light off of the valve switch. Now, disconnect the
electrical wires attached to the ring light and remove
(See Figure 4-8).
Valve Switch
The valve switch is located below the ring light. When the control knob is turned, the shaft of the burner valve
makes contact with the valve switch and closes the electrical circuit to the spark module (which provides the high
voltage spark needed to ignite the burner). To remove the valve switch you must first follow the preliminary steps
listed at the beginning of this section. Then, extract the screw which secures the switch cover and remove. Now, lift
the ring light off from the valve switch and disconnect the wiring and remove.
Light Harness Removal
The light harness is attached to one terminal of the ring light and one terminal of the valve switches. To remove the
light harness, follow the preliminary steps listed at the beginning of this section. Now, unplug the terminal connec-
tion at the ring lights and the valve switches and remove the light harness.
Harness Removal
The harness is connected to the ring lights, valve switches, spark modules and power cord. To remove the harness,
follow the preliminary steps listed at the beginning of this section. Next, unplug the harness from the power cord at
the Molex connector. Now, unplug the harness from the terminal connections at the ring lights, valve switches and
the spark modules and remove the harness.
