    Furnace short cycling Bryant Series SB C Model 100 393J
    My furnace has been short cycling.

    Bryant upflow forced air furnace
    Series SB C
    Model 100 393J

    It will run for approximately 10 to 15 seconds, shut off for approximately 1 minute, run for 10 to 15 seconds, shut off for approximately 1 minute. It does this for around 7 to 9 times then will not cycle for another 30 minutes.

    Could you please help me!
