LG ARNU093SER2 Control Board
HVAC systems will not operate lest the circuit board is installed. The control board is designed to command the gas valve, the ignition igniter, all the sensors as well as the air circulator all in one unit. The board that you will choose must be compatible with the brand and the model of the unit you have installed. Be absolutely sure while searching to pick up a replacement control board due to the many differences between systems.
How do you know if your control board is dying?

- The power to the system has to be turned off and back on frequently for the system to continue working
- Could be an a certain error code showing up on the control board
