How to replace a gas grill pressure regulator

This repair guide gives step-by-step instructions on how to replace the pressure regulator on a gas grill. A defective pressure regulator can prevent the burners from getting enough gas, or any gas at all, and the burners won't ignite. Reset the regulator as described in the owner's manual for your grill. If you’ve already tried to reset the regulator as described in your owner’s manual and the regulator still doesn’t work, replace it with a manufacturer-approved gas grill part.

This repair guide and video shows how to replace the pressure regulator in common Kenmore, Charbroil, Weber, KitchenAid, Nexgrill, BBQ-Pro and Brinkman gas grills.
