    Loose Blue Wire
    I need some help finding out where this loose wire should go. We have a 9 year old house and lennox gas furnace 80MGF series. Were not getting heat, it has a slow flash(no call for heat)on the LED code. The emergency heat will ignight the burners and we can get heat that way, but I don't want to run it to long in that mode.
    The blue wire is from a{sensor/switch or relay ?}a 2"x2" black componet, with terminal clips1 and 2 on the top and 3 & 4 on the bottom corners. The loose wire comes from the #2 terminal. Thisrelay is located a few inches to the right top of the circuit board.the label on it says48G901 24vac 50/60hz 3a 277vac coil products products unlimited.
    I'm having problems following the wiring diagram, doesn't say blue wire or show clearly the 2 relays next to the circuit board.anyway thanks if you can HELP.

    Sorry guy, but that was a very annoying post. Sounds like you have a heat pump. I think that relay was an add on by the installation company for the heat pump installation. Does the condenser run outside when you call for heat? If not just run it on emergancy for a while. Can you post a picture of the schematic and this relay? I'm going to be on vacation for a few days, but I will try to check in from time to time.

    Good luck
