Fujitsu ASU12RL2 Control Board
The control board is designed to control everything including the gas valve, the igniter, all the various sensors as well as the blower all together. The HVAC system will be unable to activate unless the control board is installed. It is imperative that you select wisely while selecting a replacement due to the vast differences in models and types. The board you choose should have a replacement part number that matches the brand and the model of HVAC system.
