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 press ignitor button. 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 conduc-
tive 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.
B. Check spark
. Pull the connector wire from the collector box
(see “X”
Fig. 46
). 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, first
replace the battery, if there still isn’t a
spark, replace the electric ignitor. If there is
a spark
the Electric
Ignitor is OK, but the Collector Box/Electrode assembly should
be replaced (the ceramic insulator could be cracked).
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. To
replace, remove the
collector box by loos-
ening the large nut
from the bottom of
the grill. Check the
gap of the new part
before installing. Loosening and tighten the two jam nuts will
move the electrode tip, set at 1/8".
Flare-Ups
Expect and encourage a moderate amount of flare-up to en-
hance flavor. To control excessive flare-ups - trim excess fat
before cooking, lower the heat setting, move meat to other side
of grill if possible, cook with lid down.
For immediate control of flare-ups, throw a small amount of
baking soda directly on the briquettes and lower heat set-
ting. Do not douse flare-ups with water, this only worsens
the flame.

Make sure Ignitor Button module is tight on the control panel.
If it is loose a good ground will not be attained.
