LG LP070HED Control Board
The LG LP070HED control board is made to operate the gas valve, the igniter, all the sensors and the blower all together. Your furnace or AC will not run unless this important circuit board is correctly installed. The proper control board should match the model number with both the brand and model of your particular system. You must be careful when you are choosing a replacement board due to so many small differences in HVAC systems.
Key clues to watch for in a failing main board
- Could be an numbered code suddenly appearing on the circuit board
- Entire unit will not initialize whatsoever
- The control board needs to be reset quite frequently for it to run
