LG ARNU073SER2 Ignition Control Board
The main ignition control board may control the main gas intake valve, the igniter as well as other safety devices. It has always been a vital electronic circuit board that has now become a vital part of the main control board instead of a separate board.
Major clues of a laboring chief ignition control board
- Initial communication from the thermostat does not reach the main board
- The ignition cycle will not begin even when called upon
- Any other potential problem throughout the system is inspected and seems to be okay
