Gas Grill: 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.

If the igniter electrode-also called the spark electrode-isn't sparking properly, first check the alignment and adjust it if it's misaligned. Clean the electrode if needed. If it's damaged, replace the igniter electrode. If it still won't spark, the battery could be weak, if your ignition system uses a battery. Replace the battery if necessary.
