Well if there is no flame the gas valve would be stuck closed.

On a call for heat use your volt meter to verify low voltage at the gas valve.

If you have voltage tap on the gas valve with the handle of a screwdriver.

This sometimes will open the valve.

If this works,replace the gas valve.

If it does not work,replace the gas valve not the control board.

If you do not have voltage at the gas valve,verify all circuits(roll out switches,pressure switches) etc. from the board to the valve.

Re-set,repair or replace the defective part.

It never gets to the stage to open the valve. It never sends power to the glow igniter

I am sorry. When you stated the high limit circuit is closed I mistook that as power to the ignitor.
