    Concord 90+ Furnace Not Stay Lit
    I have a concord 90+ furnace that tries to heat. THe burners do light, but only for about 15 seconds and then they try the cycle over. It does this five times, then quits and the LED flashes 7 times. Any suggestions. I do not have the error code list.

    Try cleaning the flame sensor. Do not touch the ignitor(the part that glows)they are sensitive.
