LG LMU180CE Control Board
The entire heating and cooling system will not activate lest the circuit board is installed. The control board is created to command the gas valve, the igniter, all the sensors and the blower all in one unit. A control board that you have chosen should have a replacement part number that matches both the make and model of the unit in question. You must be sure while choosing a new control board because of the diversity of heating and cooling systems.
Some clues your main board needs to be replaced
- Entire unit declines to do anything correctly
- System has a flashing error code randomly appearing on the control board
- Power to the control board needs to be reset quite often for it to run
