The control board I got from repair clinic online says that is one for replacement. Do you think I can replace the old board with the new one.

No. The old board size is bigger. Newer board has less number of pins than the older one.
Customer: replied 1 year ago.
Wire count or the connection point to the board on the old is much more. At least 5 or 6 leads more. approximately.

Now I have to go to attend to something. You send me an answer by text message and email. If you think that the new is compatible then can you suggest how to wire. The problem I have is this. When system starts fans are turned on. After a few seconds igniter glows. I hear a click and gas starts jetting out through several burners and gets ignited. Then after a few seconds the igniter stops glowing and the gas valve closes and the flame shuts off. Last year a technician recommended replacing the control board. So I replaced this.

It is going to be almost 22 hours. Still I have not received any response to my problem. Is it that complex that my problem can not be solved ? Please respond if you can handle my request or not.
