    Hmm

    have a ducane, CMPA050U3 furnace and the unit is running a long time, supply plenum doesn't get hot, flame not being drawn into exchanger hard, seems a little lazy, but heat exhanger was changed two years ago, secondary ? bad?

    ducane

    Ducane residential furnace production is actually a Lennox owned company, not Janitrol or Goodman. You really did not provide enough information for a diagnosis, what is your rate and rise? Delivery temperature at the supply registers?
    Why was the heat exchanger replaced? Was the draft inducer assembly and/or gasket replaced? This info will give you a starting point at least..
