Your Solaire ignition system consists of 2 components: The spark generator and the igniter wires & electrodes. The spark generator is what you push or turn to ignite your grill and the electrodes are places next to the burner holes to create the spark.
Older Solaire Grills used a AA battery holder system that has been discontinued and replaced with a battery holder/push button spark generator system. Newer Solaire Grills use a 2 port or 4 port 9v Spark Generator
The Igniter Module is located under the Front Control Panel on the left side in the 21”, 21XL grills. It is on the Right side in the 27”, 27XL, 30”, 36” and 42”, and one on each side for 56” and 56T models.
Be sure to check that the Igniter Wires are securely connected to the back of the Spark Generator. If their is still no spark, you may need to adjust the metal tip closer to the burner.
