On the way home I had a thought. I should have removed one of the block off discs to verify air is pushing from the unit. That thought came after 2 hours of driving:)
Those block off discs, are knock out plugs, and once removed will not stay back in.
Be very careful what you use to push down a duct as it is quite likely you could poke a hole in it.

Actually the plugs are discs that have an indexing tab and twist to lock.
That is my concern about poking in the duct work. I assume to access the duct work you must pull up the floor? Lets not go there yet :D
Sorry, those are KNOCK OUT PLUGS. The Indexing tabs are used for the 4 inch metal collar that HAS a Tab to go into and turn to lock it in. You can knock them out, but NOT NEEDED for your problem. If you do knock them out just use metal foil tape to reinstall and block the hole. It is a whole lot easier to take the furnace loose and lift it up to see what and how the furnace is connected to the in floor duct assbly. Doug
