    Dan here... Serviceman that did install says it is probably the small fan that clears the fumes from box NOT starting (it didn't... just a hummm from the entire unit)... the code is described as "pressure switch stuck open"... he says sometimes just a nudge of the squirrel cage will set it free and be good to go... we'll see... he is checking it now... Dan H.

    Addendum... that was it... easy fix... just gave the old squirrel cage a VERY slight nudge... operation is RESTORED... no parts required... hope this helps others... Dan Habluetzel.
