Fujitsu AOU24RLXFZ Control Board
The Fujitsu AOU24RLXFZ control board is made to operate everything including the gas valve, the igniter, all the sensors as well as the blower all in one unit. Heating and cooling systems will not even operate without the board properly connected to the unit. The proper control board will have to be compatible with both the make and model of HVAC system. You must do some research when you decide to replace your control board because of the diversity of heating and cooling systems.
Key indicators that my primary control board needs replacing?
- The control board has to be reset quite often for it to run correctly
- There is a fault code being displayed somewhere on the circuit board
- The HVAC system does not initialize whatsoever
