Rotary Spark Ignitor System
If you experience an occasional “No-spark-No light” condi-
tion here’s a check list to troubleshoot the problem.
1. Inspection. WITH GAS OFF,
position a mirror in front of the
collector box and rotate the ignitor knob several times. Observe
the condition of the spark. (Low light conditions are the best for
seeing the spark.)
A. If there’s a good spark
, but the grill
won’t light, gas may not be flowing to the
burner and into the collector box. The gas
orifice or the venturi tube may be blocked.
To clean, follow “Flashback” instructions.
B. If a weak spark arcs down around the
ceramic insulator
, the insulator should be
cleaned. The insulator has a coating of
grease or it is wet. Use an old tooth brush
to break up the conductive electric path.
2. If there is no spark in the
collector box
.
A. Check the wire connections
at the ignitor and electrode
under the grill. Lubricating
(use WD-40 or equivalent)
the star wheel and tension
spring of the ignitor will help
connection contacts and im-
prove operation.
B. Check spark
. Pull the connector wire from the collector box
(see “X”
Fig. S
). Bring wire to bottom or top of control panel,
hold about 1/8" away and operate the ignitor. Check for spark.
If there is
no spark
replace the Rotary Ignitor. If there is
a
spark
the Rotary Ignitor is OK, but the Collector Box/Electrode
assembly should be replaced (the ceramic insulator could be
cracked).
C. Check Knob
, confirm quality of the electrical ground at the
Rotary Ignitor. Remove the knob, loosen and retighten the
mounting screws.
Electrode Replacement or
Adjustment
The electrode inside the
collector box is pre-set for
optimum spark. The tip is
1/8" from inside surface of
the collector box.
Check the gap of the new
part before installing. Loos-
ening and tighten the two
jam nuts will move the elec-
trode tip, set at 1/8".
