The HVAC system will be unable to run at all without the control board hooked up and is correctly configured. The Friedrich MR12C1H control board is designed to command everything including the gas valve, the ignition igniter, most sensors as well as the blower all together. The proper control board must be compatible with both the make and model of your Friedrich MR12C1H unit. It is imperative that you select wisely while choosing a new control board due to so many small differences in models within certain brands.
