Fujitsu AOU36RML Control Board
The control board is created to oversee everything including the gas valve, the ignition igniter, all the sensors as well as the air circulator all at once. The system will cease to be able to function unless the control board is properly connected to the unit. You must do some research when choosing a control board because of the diversity of brands, models and types of systems. A control board that you have chosen is supposed to have a part number that matches both the make and model of the system you have installed.
Key clues of an ailing main circuit board
- There is a fault code revealed on the board
- AC unit or heating unit ceases to do anything well
- The control board has to be turned off and back on quite a lot for the thermostat to kick in
