How to Check a Grill Ignitor
The ignitor on a gas grill triggers a spark to light the burner inside the appliance in preparation for cooking. Ignitors typically work with a wire from a spring-loaded push button on the grill control panel to the ignitor component installed on the underside of the grill. Pressing the button sends a small electric charge to the ignitor, which produces a spark that lights the gas around the perimeter of the grill burner. If you are having trouble with the ignitor, there are several ways to troubleshoot the problem.
- Push the black wire firmly onto the terminal on the back of the ignitor button where it is mounted on your grill control panel, using needle-nose pliers. The wire is installed with a metal clip that connects to the post on the back of the ignitor.
- Push the other end of the wire onto the ignitor module, which is mounted below your grill under the burner. The ceramic ignitor cylinder resembles a spark plug.
- Rub a small piece of steel wool over the tip of the ignitor under the grill to remove any grease or dirt that could prevent it from operating properly.
- Turn the knob on the gas tank clockwise to shut off the fuel while testing the ignitor.
- Press the red ignitor button on the front of your grill control while peering below the grill to watch the ignitor beneath the burner. With normal operation, you should see a spark flick off the tip of the ignitor when the button is fully pressed; it should make a sharp clicking sound. If these tests fail to produce a spark, the ignitor may be bad. Replacement ignitor assemblies are available at grill shops and hardware stores.
