Gas Furnace Ignition Control Modules!

In this HVAC Gas Furnace Video, I go over pilot ignition control modules, direct ignition controls, and how they differ from an all-in-one Integrated Furnace Control Module. I explain how the single rod spark ignition control works, how the two-rod spark ignition control works, how the direct hot surface ignition control works, and how the direct spark ignition control works. I also go over how the flame proving process works and the voltage flow during the sequence of operation.
