Tube off the pressure switch is clear, I blew into the pressure switch and into the fan housing. Made sure the vent was clear as well. Still only lite the pilot for 5 seconds and didn't not try to ignite again.

I think you're at a point you either have to review your process and procedures, and see if you have missed something, or get fresh eyes on the problem. At this point I recommend both. Learning is a difficult enough of a process in of itself, and learning about a furnace takes many hours of instruction even for those with skills.

Please keep us updated on your progress. Good Luck. Sorry I was of no help.

Well, I order an igniter module and put in... turns out that was the problem furnace is now running. Thank you for all of your help

Boy am I glad you got it. Please if you have time, explain how you arrived at the igniter module as the problem?

[Libke57]

Well I checked all the sensors, then it occurred to me that the furnace would only try to cycle once and it was supposed to try every 90 seconds for 5 minutes, so I took a stab in the dark and turns out that I got lucky... still going good!

Thanks for getting back to us. LOL, I rather be lucky than good myself. 8D! I thought we checked that ignition module with the gas valve. Oh well, we can till celebrate with your savings.
