LG AMNC093D4A0 Control Board
The HVAC system will be unable to run at all without the board in connected and operational. The LG AMNC093D4A0 control board is constructed to control the gas valve, the igniter, the flame sensor and the blower all in one unit. The chosen circuit board is supposed to have a part number that matches both the make and model of the unit in question. You must be sure upon choosing a board as a replacement due to the many differences between particular brands and their models.
Signs your main board is in dire straights
- Everything has to be turned off and back on frequently in order to continue running
- There seems to be a fault code displayed on the circuit board
- The entire system ceases to function period
