It has 2 pressure switches? Did you blow threw the tubes to get any moisture out?
Did you check to see if the vent was clear?
Thanks Josh,
Yes, I checked and replaced both. Also I blew through the tubes. The furnace was 1 of 4 systems in this development and start up was for the first time yesterday.
Today I am going back to check to see if I have 24v going from pin 2 on the connector traveling to my PS.
Any other ideas let me know. I'll post my outcome tonight.
