Spiders in the venturi

Clear the spider screens

Spiders and insects build webs in the burner inlets (the venturi), and that starves the flame. Each burner end has a spider and insect screen (the manual).

1. Let the grill go cold and turn the gas off.
2. Open the doors and look up under the control panel.
3. Find where each burner tube meets its valve.
4. Clean the screen there with a soft brush.
5. Do every burner end, the Sear Zone's too.
6. Relight and check the flame runs the full length of each burner.

Signs of a blocked inlet: yellow, lazy flames with a smell of gas, uneven heat, or a burner that will not light (the manual).
