See the most common gas grill repair parts below.
Electric spark control module
The electric spark control module—also called the igniter module—creates a spark that arcs to the burner to ignite the gas when the burner is on. The electric spark control module has either a battery or a piezoelectric system.
Here’s a video that shows how to replace the electric spark module on a common gas grill.
Igniter electrode
The igniter electrode receives electrical current from the igniter module and produces a spark between the tip of the electrode and the burner to light the gas during the ignition process.
Watch our How To Replace an Igniter Electrode on a Gas Grill video to guide you when replacing this part.
Main burner
The main burner of a gas grill—also called the burner assembly or burner tube—is a metal tube with small holes on each side that distributes the gas through the holes to create an even flame across the cooking area. The gas grill main burner mounted in the fire box, under the grates and flavor bars.
Our Replacing a Burner on a Gas Grill video shows how to install a main burner on a common grill.
Pressure regulator
The pressure regulator on the supply line from the propane tank controls the pressure of the gas going to the grill. It often includes the gas supply hose and the fittings that connect the propane tank to the manifold.
Follow the steps in our Replacing a Pressure Regulator on a Gas Grill video to install a new pressure regulator on your grill.
Grill manifold
The manifold on a gas grill holds the burner control valves and the connecting gas tubing that are mounted on the front of the grill. The gas supply hose connects to the supply tubing on the manifold. The valves control the gas flow going to the burners.
Gas collector box
The gas collector box on a gas grill is a partially enclosed box at the inlet to the burner tube that accumulates gas during the ignition process. The igniter electrode ignites the gas accumulated in the gas collector box.
Firebox
The firebox on a gas grill is made of a heavy-weight metal and houses the burner, flavor bars and grates. The gas valve manifold is mounted on the front of the firebox.
Burner bracket
The burner bracket on a gas grill holds the main burners in place.
Grill accessories
Grill accessories help make backyard cooking easier and more convenient. Adding tools sets, rotisserie gear, roasting racks and grill-top griddles can help you elevate your grilling performance. Cleaning supplies and protective covers can help keep your grill in top shape.
Troubleshooting problems and replacing parts, or adding accessories will help you keep your grill fired up so you can cook the best meals ever.
