A look at several spark ignitor ignition controls for gas furnaces. What they are used on. How they cycle. Basic troubleshoot of failures. These are not integrated furnace controls and are used on units with pilot burners to eliminate a standing pilot.
This video is part of the gas furnace series of training videos made to accompany my website: www.grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome.
If you are a homeowner looking to repair your own appliance, understand that the voltages and fuels used can be lethal and can cause a fire or explosion. Know your limits.
