Keep Your Automatic Ignitor Igniting!

How does the automatic ignitor in my gas grill work?

The ignitor is a unique piece of technology.  The core of the ignitor is a piezoelectric crystal.  The piezoelectric crystal generates an electrical charge on its surface when it is subjected to pressure.  The more abrupt the pressure, the greater the power generated.  So turning the knob (or pressing the button) on the ignitor control snaps a tiny spring-loaded pin against the crystal.  The ignitor then sends this high voltage electrical charge along the wire to the ignitor electrode, located inside the collector box.

The collector box has two functions. 

First, it provides a surface for the electricity produced by the ignitor crystal to arc.  Second, it acts as a open container that "collects" gas to provide a good medium for combustion.  When you push the ignitor button, electricity sent to the electrode jumps from the electrode to the top of the collector box, producing a spark which ignites the gas in the box and also in the burner.

If your grill has an ignitor that no longer works...

Now that you understand how the ignitor works, troubleshooting is much easier!  Here are some tips to determine whether you need to replace the ignitor:

Time to replace the ignitor?

If you've tried all the steps above and the ignitor still does not produce a spark, then it's time to replace it.  Appliance Factory Parts can help you get the right replacement part for your grill!
