The HVAC system will be unable to activate lest the main control board is configured and seated properly. The control board is designed to control everything including the gas valve, the igniter, most sensors and the blower all in one unit.

Be very careful upon choosing a board as a replacement due to so many small differences in brands, models and types of systems.
