I must tell you . You have helped me tremendously . Your videos are cleared and easy to understand. You are not arrogant with you knowledge. I respect that . Thank you for sharing.

Thanks Sam for taking your time for explaining it..

As a journeyman gasfitter in canada, I think this is a good video as it uses a fairly basic furnace and does a good job of explaining how to read a wiring diagram. Between the sequence of operation, wiring diagram, using the correct equipment to diagnose power, vent pressure, gas pressure and combustion, near any problem can be solved! Good job!

Awesome video Sam. Schematics are definitely my weak spot and I will watch your video a few times to clear up some issues i'm having. This is very helpful. Thanks
