How to fix your Wards gas grill when some burners won't light
When one or more burners won't light, clogs in the non-working burner tubes are often the cause. Remove the grates and the flavor bars and check the non-working burner tubes for clogs such as spider webs inside the burner tubes. Check the ports on the sides of the burner tubes for clogs as well, or for damage.
If the grill has an igniter for each burner, look for cracks in the ceramic insulators of the igniter electrodes that can cause the electrodes to fail. Check wiring connections on the igniters. Reconnect any loose wires and repair any broken wires.
Test the ignition module and replace the ignition module if it isn't sending spark current to the affected burners.
A failed grill manifold could also prevent some burners from lighting. Replace the manifold if it doesn't allow gas flow to the affected burners when you turn on those burners' gas valves.
Commonly replaced Wards gas grill parts
- 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.
- Main burner. The main burner of a gas grill 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 main burner is mounted in the fire box, under the grates and flavor bars.
- 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.
- Burner bracket. The burner bracket on a gas grill holds the main burners in place.
