I am a gas grill technician and your barbecue ignitor is fine.   Although we only sell American made grills with available replacement parts and reliable warranties, we provide technical service and cleanings for any barbecue. Whether a grilling customer has a great grill or a cheap import, one thing I frequently is: “the igniter on the barbeque grill stopped working within the first year”.

Sometimes “the first year” was ten years ago!! Although the grill may not ignite at the push of a button, the cause is rarely a broken barbeque ignitor. Ignition systems generally work reliably for many years but may need replacement grill parts inside the firebox of the barbeque.

Of course, you could point out the obvious confusion in that statement which is that if the grill stopped igniting, what does it matter if you say the igniter is not broken?!

If it does not ignite the grill, it is not working.  I have been shocked by ignition modules off grills when the owner claimed the ignitor hadn’t worked in ten years.

A Gas Grill Igniter Is Made Up Of Several Parts.

A gas barbeque grill ignition system consists of several replaceable parts.

The module, the electrode wire and the electrode are the primary parts although sometimes the module will be split into a spark generator, a connection switch (button) and a power source (battery). The electrode is like the spark plug in your car, the part that mounts on or near the gas grill burner and sparks to light the grill. The electrode is usually the culprit when you cannot light your grill.

The gas BBQ ignition module, or spark generator, is the part that creates the juice. Many older gas barbeque grills used a piezo electric module. These simple ignition modules would last forever. However, most gas grills today use a battery-powered module. Ignition modules with batteries can corrode from moisture but it is not as common as most of us assume and it can usually be cleaned off. An electrode wire connecting the ignition to the module delivers the spark to light your gas grill. You should be able to see the steel running through porcelain in the front of the firebox just above or beside the gas grill burner. Sometimes the electrode will have another rod as a ground, others ground to (spark against) the stainless steel burner. The power from the battery ends as a spark at the tip of this steel rod. If the gas is on, this arc should ignite your gas grill burner.

Troubleshooting

If your gas grill will not ignite, there could be a few different reasons. Low gas flow is often caused by the check valve in the lp tank. To correct this issue read: Why won’t my gas grill get hot? Rarely a gas regulator may need to be replaced. If you have been grilling on this gas BBQ for over five years, have a professional test your regulator. However, the most common problem we see is in the ignition system.

What is wrong with the BBQ Grill Ignitor?

As you cook on your gas barbeque grill, the heat trapped in the hood causes the food to “sweat” and grease drips into the grill. As grease and sauce come off the food to make their way to your drip-pan, the inner machinations of the grill get dirty. When the grease, pieces of food, rust, rain water, dust and dirt get in to the firebox the electrode gets too dirty to spark. If you take away one bit of advice from this message: if you do not hire a professional to clean your grill, don’t just clean the parts you can see or eat off.

Make the gas grill ignite.

As part of your maintenance, look for the electrode inside the firebox of your gas barbeque. It is usually inside the firebox on the front wall near the control panel. A stainless collector box may cover the electrode to protect the electrode from grease and weather and to protect the spark from too much wind. Gas grill igniters that use a collector box often use the box to spark against the electrode and act as the ground. When grease, rain, sauce, etc, drip onto and into the ignition collector box, the electrode has a problem finding steel to ground it and spark. The module, battery and switch are still functioning to send the spark to the gas but the failure is at the electrode. If the electrode or collector box is too dirty to get a clear spark, the gas will not ignite.

Gas barbecue grill manufacturers make these products to be outside in the weather. They are made to be functional in the snow and rain. When you clean your gas grill, simply knowing the parts of the igniter should give you the ability to ensure the electrode stays clean and your gas grill ignition will last much longer.
