My Goodman GMP series furnace will not lite. The inginiter glows but the burners will not lite. I am not getting the 24V to the gas valve. I can put 24V to it and all will work until the next time the thermostat call for heat and again the inginter will lite but the burners will not. You can hear the relays operating on the circuit board but I still do not get the 24V to the gas valve.
