Maintaining a Rotary Ignitor System

If you experience an occasional “No-spark-No light” condition here’s a checklist to troubleshoot the problem.


Troubleshooting IGnitor System

A weak spark will arc down around the ceramic insulator

Troubleshooting Ignitor System | Good Spark

A good spark will spark at the top

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.)

  • 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.
  • 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 toothbrush to break up the conductive electric path.


If there is no spark in the collector box

Check Wire Connections
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 improve operation.

Troubleshooting Ignitor System | Check the wire connections

Check spark
Pull the connector wire from the collector box (see illustration below). Bring wire to the bottom or top of the 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).

Troubleshooting Ignitor System | Check spark

Check Knob
Confirm the quality of the electrical ground at the Rotary Ignitor. Remove the knob, and loosen and retighten the mounting screws.
