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 as shown in this video 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.

These repairs may help solve your Gas Grill problem:

Clean, repair or replace the gas grill burner

Main burner

Regularly check and clean the burner tubes of spider webs and debris. Clean the burner tubes with a bottle brush or stiff wire, such as a straightened coat hanger. Check the gas ports (holes) for spills that could glog them. Clean the burner if necessary. Look for rust or damage on the burner bodies and replace a burner if it's damaged or rusted.

Clean, align or replace the gas grill igniter electrode

Igniter electrode

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. If the igniter still won't spark, the electric spark control module might need to be replaced.

Replace the gas grill manifold

Grill manifold

The manifold on a gas grill has the burner control valves and the connecting gas tubing. If the manifold fails, burners won't heat sufficiently or won't light at all. If a valve is stuck and not working, replace the valve. If the individual valve isn't available as a separate replacement part, replace the entire manifold.

Repair or replace the gas grill ignition module

Electric spark control module

Check the wiring connections between the ignition module and the igniter electrodes and repair any broken wires. If the spark control module has a battery, replace the battery if it’s dead. Test the ignition module using a multimeter and replace the ignition module if it isn’t sending spark current to the igniter electrodes.
