LG AMNH123DEA0 Control Board
Most systems will not operate lest the circuit board is in its proper place and configured for your unit. The control board is constructed to operate everything including the gas valve, the ignition igniter, all the sensors and the blower all together. The board you select should match the model number with both the make and model of your LG AMNH123DEA0 unit. You must be careful when you are choosing a replacement board due to variances between particular brands and their models.
What are the indications that my main board is failing?
- Power to the circuit board has to be reset quite a lot in order to continue running
- The furnace or AC does not run properly
- There seems to be flashing code revealed on the circuit board
