Samsung AVMBH040CA0 Ignition Control Board
The main reason to have an ignition control board is that it regulates gas flow, the ignition timing and other safety devices built into the system. It is an important electronic safety board that is now usually a standard part of the main board for enhanced safety.
Major signs the ignition board is on its last leg
- Any other problem in the system is inspected and seems to be in good condition
- Initial communication from the home thermostat never moves to the Samsung control board
- The main ignition cycle fails to kick in even when the thermostat kicks it on
