Nice Video, I just wanted to share with you a new tool I've invented that accurately tests pressure switches without the furnace even running. It works by simulating the Draft Inducer. With a manometer attached you can find out exactly when the switch opens and closes, thus proving it's working properly. You can also find out if there is a weak diaphragm, and CALIBRATE adjustable pressure switches! I posted it as a video response, I hope you like it!

I just had a bad snow storm that dumped 17.5 inches of snow in the area and the pipes/chimney were plugged on the roof for the furnace from the snow so i had to wait for the snow to melt and it worked, I was getting the LED status error code 31 because of the plugged pipe for the inducer I believe.

If the flew is stopped up, there is not a negative pressure to pull in the switch. It sounds like you figure out your problem. We only got 10 " of snow so it was not that big of a problem with the flew on my roof for my 90%
