Will narrow the problem down quicker and you can tell them what light sequence you are seeing so repair guy will have correct parts on him and not have to make a return trip.

Ya, I saw those blinking lights as well as the legend. 'pressure switch open with inducer on' is the indicator. I looked at a YouTube video before the service call and it was over my head! I'd hope the repair guys know how to follow the indicator lights and legend!
Anyways, quick update, from the time the repair guy booted it back up with the new pressure switch to the time I got home with the insulation, it had already crapped out again. He's swinging by one more time tonight to boot it up and to hopefully see if the insulation will do the trick. Wish us luck through the night!
Between the 3 space heaters we 'borrowed', we were able to keep it at 18 degrees through the early evening, so that's a plus.
