LG ARNU093SEL2 Control Board
Your air handler will be unable to operate whatsoever lest the main control board is in connected and operational. The LG ARNU093SEL2 control board is created to command everything including the gas valve, the ignition igniter, the flame sensor and the blower all in one unit. The proper control board should match both the brand and model of the unit you have installed. You must do some research when you choose a control board due to so many small differences in systems.
Indications of an inadequate control board
- Your HVAC unit refuses to run at all
- The system board has to be reset quite frequently for the furnace or AC to kick on
- There may be a strange type of error code indicated directly on the board

If you are going to be buying or purchasing, do your due diligence and double check the model number and also make a visual inspection in order to be sure the correct replacement control board is being ordered. If you are unsure about the correct way of installing the new control board on your own then it is probably best to consult a pro to do the work for you.
