LG ARNU243TLC2 Control Board
The LG ARNU243TLC2 control board is created to operate everything including the gas valve, the ignition igniter, all the sensors and the blower all together. HVAC systems will not operate whatsoever without the board properly connected to the unit. Be very careful when you are choosing a replacement board due to differences in certain brands. The board you choose must be compatible with the brand and the model of your particular system.
Symptoms of a declining primary control board
- Your HVAC unit will not function whatsoever
- Power to the circuit board has to be powered down and back up quite often for the system to operate once again
- There seems to be numbered code shown directly somewhere on the circuit board
