LG ARNU153SEL2 Control Board
The control board is constructed to operate everything including the gas valve, the igniter, most sensors and the blower all together. Your air handler will be unable to operate whatsoever lest the circuit board is in connected and operational. Be absolutely sure upon picking a replacement board due to the vast differences in particular brands and their models. The board that you will choose should have a replacement part number that matches both the brand and specific model of your particular system.
