LG ARNU073SEL2 Control Board
The LG ARNU073SEL2 control board is designed to control everything including the gas valve, the ignition igniter, most sensors and the blower all in one unit. Most systems will not function without the board in place and connected. Be very careful when you are deciding on a replacement because of the many variances of models within certain brands. A matching board must have a matching part number consistent with the brand and the model of your heating and cooling system.
How do you know if your main board has a need to be replaced?
- The HVAC system refuses to operate correctly
- Power to the control board has to be powered down and back up all the time for it to run
- Could be an error code lit up somewhere on the board
