Fujitsu ASU30CLX1 Control Board
HVAC systems will not activate lest the circuit board is in place and connected. The Fujitsu ASU30CLX1 control board is made to regulate everything including the gas valve, the ignition igniter, most sensors as well as the air circulator all at once. A matching board will need to pair with the part number from both the brand and model of the unit in question. You must do some research when you decide to replace your control board due to so many small differences in systems.
Easy warnings of a weakening main circuit board
- The HVAC system is unwilling to go whatsoever
- Power to the control board has to be reset frequently for the heating or cooling to kick in
- There is a numbered error code being shown on the board
