I have a York P2UR furnace (LP) that is not blowing hot air. The ignition sequence seems to cycle properly with the exception of flame. My HVAC guy has done a lot of troubleshooting and did get it fire once after breaking the intake tube. Now we have both the intake and exaust tubes broken and cannot get a flame.

I am getting a 7 blink fault code but don't see that particular code in the manual... can anyone help?

7 Flash. Lockout caused by no ignition.

It could be ignitor,circuit board, among other items. It seems you need to find a better HVAC guy that knows what he is doing.
