    Armstrong ultra sx 80 furnace no pilot light
    We've had a problem the last 2 winters with our furnace, always fixed but last night the furnace stopped working. We checked and there was no pilot light. Actually in this model we don't even know where we would light it. Someone told me it might be the thermo couple but I am in need of another opinion. Any suggestions?

    Thanks:confused:

    Verify that you have 24 volts ac from the transformer then
    Jumper the R and W terminals on the board and see if the furnace runs okay or not (this eliminates the thermostat).

    Post back with results.

    Thanks for the post. We couldn't figure it out by ourselves so we called someone out. Apparently one of the lines was full of rust and needed to be drilled out so the gas could pass through. So it was an easy fix but we would have never found it. Thanks for your help though.

    :D
