LG LMU360HE Ignition Control Board
The main reason to have an ignition control board is that it has control over the natural gas, the ignition timing and other safety devices built into the system. The ignition control board was always an important safety feature that, over the years, has merged to become a part of the main control board for the sake of being more efficient.
What warnings are present when my main ignition board has to be replaced?
- The primary ignition sequence fails to fire up at all
- Any other problem within the heating and AC system is researched and comes to be OK
- Initial communication from the main thermostat does not get to the main control board
