    Pressure switch problem in furnace
    Please help.. I've looked at other forums but still can't find the answer. I'm getting a pressure switch error and I have done a few things already..
    1. Took the tubing off going from inducer to switch and sucked the side going to the switch.. It sucks freely for a short period then closes up with a clicking sound.
    2. Sucked the end going to the inducer and there is no airflow at all. Inducer off
    3.dettached the exhaust and found excellent airflow with no blockage.
    4. Replaced switch

    Still reading the same error that pressure switch tried 5 times and heat won't come on

    Take the hose off the inducer & use a nail, drill bit, or stiff piece of wire to clean out the hole in the nipple to which which the hose connects. The "tool" should go in the depth of the nipple plus at least 1/2".

    is it supposed to be free flowing air with the inducer off?
