Weber Genesis II Parts

Weber grills are some of the most popular gas grills on the market. Known for their quality construction and excellent grilling performance, Weber grills like the Genesis II series are built to last. However, like any grill, parts may need replacing over time due to normal wear and tear. This article will cover replacement parts for the Weber Genesis II gas grill line.

Grill Parts

The heart of any grill is the grill itself. For the Weber Genesis II, there are a few key components that may need replacing over the life of the grill.

Cooking Grates

The cooking grates are one of the most frequently replaced grill parts. Weber cooking grates are made of high quality stainless steel that distributes heat evenly. However, the intense heat and abrasive cleaners can cause the grates to slowly deteriorate over several seasons of use. Replacing damaged grates helps ensure even cooking and those trademark Weber grill marks.

Weber offers porcelain-enameled cast iron cooking grates as an upgrade option. These grates retain heat exceptionally well and have a non-stick surface for excellent food release. Porcelain enameling also makes the grates very easy to clean.

Flavorizer Bars

Weber’s angled flavorizer bars are what set their gas grills apart from the competition. These bars are positioned above the burners and are designed to vaporize drippings and infuse smoke flavor back into the food. The bars also protect the burners from getting clogged with grease and debris.

However, the flavorizer bars bear the brunt of the heat and fat drippings. Over time, they can become rusted, cracked or misshapen. Replacing worn flavorizer bars restores safety, performance and that delicious smoky Weber flavor.

Heat Deflectors

Found between the flavorizer bars and the burners, heat deflectors prevent grease from coming into direct contact with the burners. Made of stainless steel, these parts need replacing if they become excessively grease-laden or deteriorated.


The gas burners are the source of heat for gas grills like the Weber Genesis II. While burners typically last many years, normal wear and tear can degrade their performance over time. Replacing old burners restores heating power and distribition for more efficient grilling.

Weber burners are made from stainless steel for durability and feature a tapered shape to deliver even heating across the entire cooking surface.

Gas Parts

In order for a gas grill to function properly, all the gas components have to be in good working order. These parts facilitate and control gas flow.

Gas Valves

Gas valves regulate the amount of gas that goes to the burners. If a valve is showing signs of wear or improper gas flow, replacing it ensures safe burner operation.


The regulator controls the pressure of gas from the LP tank to the grill. Regulators have seals that degrade over time and should be replaced roughly every 5 years. This helps keep gas flow at the optimal pressure.

Gas Hoses

The gas hose connects the regulator to the grill’s valves and burners. Weber hoses are made from stainless steel braiding for durability. Checking for cracks, damage or loose connections and replacing worn hoses reduces risk of gas leaks.


Ignition systems light the burners electronically and may need replacing if they become unresponsive. The most common igniters are push-button and crossover designs.

Grill Hardware

The various nuts, bolts, hinges, doors and other hardware parts see heavy use during grilling season. Replacing any components that have rusted, broken or otherwise deteriorated keeps the grill sound and safe.

Lid Hinges

Weber lids are on heavy stainless steel hinges that provide smooth opening and closing. But the hinge springs can wear out over time. Replacing both springs keeps the lid operating properly.

Lid Handles

Handles take the brunt of opening and closing the lid. Stainless steel construction makes Weber lid handles very durable. But extreme heat and abrasive cleaners can damage the finish over time, making replacement necessary.


Access doors in the shroud protect the gas valves and propane tank. But constant opening and closing can loosen the hinges or cause the doors to sag over time. Replacing doors keeps access clear to the grill’s vital components.

Control Knobs

Weber control knobs have an iconic look, but their plastic construction makes them susceptible to cracking and fading. Luckily, replacing faded or damaged knobs gives the grill a facelift and makes controlling the burners easier.

Accessory Parts

Weber offers a wide selection of grill accessories designed to enhance the grilling experience. Many accessories either wear out or get damaged over time.

Porcelain-Enameled Warming Racks

Warming racks provide room for toasting buns or keeping the food warm while the rest of the meal cooks below. But dropping heavy foods can chip the porcelain over time. Replacing a damaged warming rack restores full grill functionality.

Stainless Steel Side Tables

Side prep tables create extra workspace next to the grill. Weber side tables feature stainless steel construction and gas models offer the option of a side burner built-in. Replacing worn tables gives you a sturdy and durable food prep surface.


Mounted in the lid, grill thermometers let you monitor internal temperature. However, opening the lid repeatedly can damage the probe. Replacing the thermometer allows you to keep close tabs on temperature for optimal results.

Weber Covers

From water-resistant to full waterproof models, grill covers protect your investment when not in use. But constant exposure to the elements causes deterioration over time. Replacing faded and ripped covers helps keep your Weber grill looking great season after season.
