Cant figure out this furnace problem, I have 24 volts at gas valve so installed new one and now I can hear the valve kick on and it kicks off immediately. Tried a new control board next and that didnt work either. Probably something simple that I made difficult. Unit probably 30 years old and high efficient.

    Before replacing every thing,

    You need to check your pilot flame signal...  Also find out where your voltage to the GV is dropping out.  Pressure switch may be at fault.



    Peace;
