LG LMAN120CNS Control Board
The LG LMAN120CNS control board is designed to direct everything including the gas valve, the ignition igniter, most sensors as well as the air circulator all in one unit. Your air handler will be unable to operate unless this important circuit board is correctly installed. Be very careful when you decide to replace your control board because of the many variances of brand and air handler types. The chosen circuit board will have a part number that will match both the brand and specific model of furnace or air handler you have.
Clues to watch for to know your control board is in dire need of a replacement
- The control board has to be powered down and back up all the time for the system to continue working
- Air conditioning or heating system does not operate properly
- There is a strange type of error code instantly appearing somewhere on the circuit board
