    Locating the pressure switch
    I have a Nordyne furance and the LED light is flashing #2. Also what should I do when I do find it? I don't have a manual for this and I don't have the first clue where to look. Please help I have never had to do anything like this before. Thanks!

    The pressure switch, I found it disconnected one of the hoses. I blow in to one of the hoses, when I did that the light stayed on. DO you think the hose needs replaced or the switch?

    You need to be sure the hose is clear of all debris. Reattach and cycle main power supply. (turn unit off at power switch and back on). See what it does.

    The light on simply means the power is turned on to the unit. If you have a meter you might start checking the low voltage circuits starting with the thermostat.
