    Trane model number find control board 50a50471
    The code indicator on the board 5 times in a series indicating a problem with the flame sensor. Replaced flame sensor and 24hrs laters the code indicator is flashing 5 times in a series again. What would be the solution?

    Make sure all contat points dealing with ground or the flame sensing circuit are clean & tight. Also check that the flame is hitting the sensor well.
