    The inducer pressure is dropping. Check venting, inducer wheel, and pressure sensing port.

    Good luck.

    similiar...

    Had a system do this..found that the venting had a dip in it that was trapping water...used a hanger to pull the vent back into a straight line, which allowed the built up water to drain in to the pump and have never been back...
    stay warm..:)

    Cleaning

    I would start by cleaning the trap, cleaning the port on the inducer draft. Have you hung your Mag gauge on the on inducer draft fan and checked the pressure? Assuming closed combustion have you tried to run the machine with the combustion chamber open ? How's the flame sensor? is the donut or seal/gasket damaged for the IDF? Best wishes J. Lockard
