We've all changed countless ignitors in gas ovens, and any tech worth his salt knows that the definitive way to detect a failed ignitor is with a current measurement. But why does low current through the ignitor cause ignition to fail? Where does that current spec come from?
In this short excerpt from one of our many technical webinars, the Samurai explains the mechanism behind how these gas valves work. Not only will it give you a clear idea of the technology behind these common parts, but it will give you insight into why smart techs troubleshoot these appliances the way they do.
