Fujitsu AOU12RL2 Control Board
The HVAC system will be unable to operate unless this important circuit board is in connected and operational. The control board is designed to command everything including the gas valve, the igniter, all the sensors as well as the air circulator all together. The selected board must be compatible with both the brand and specific model of HVAC system. It is imperative that you select wisely while choosing a new control board due to so many small differences in systems.
What are the clues to watch out for to know my control board really needs to be replaced?
- Air conditioning or heating system is unable to work correctly
- The board has to be reset a lot for everything to run again
- Could be an some sort of code suddenly appearing somewhere on the board
