    Bryant furnace starts then stops
    My Bryant forced hot air furnace gets the signal to ignite, the pilot light and then the furnace lights but it goes out in a few seconds. This will happen over and over and then occasionally it might stay lit and warm the house. Any ideas of what this could be and how to fix it.

    Much appreciated.

    Replace the circuit board, they are known to be the problem.

    I would try cleaning the flame roll out switch before blowing the big bucks on a board.

    There is a flame sensor, it is a wire looking thing sticking up in the flame on the burner to the far left. It has a ceramic base. Take this out and sand paper the wire... do not bend it or the ceramic will break... Let me know if this helps.
