    Concord gas furnace 6 LED flashes
    I have a Concord System 80 Gas Furnace that is not blowing any heat out. The LED is flashing 6 times. What does this mean?

    Look on the back side of the blower motor access door for the legend (number of blinks or flashs). Every furnace has this diagram and it will tell you what the code is for your brand of furnace.

    I did and there was no code for 6 flashes listed. Service tech came and discovered that the ignitor was bad. He replaced it and the furnace is back up and running.

    At least you got it up and running. Without codes from the unit it is just about impossible to tell what is going on from a long distance.
