International Comfort Products N8MPL050B12A1 Ignition Control Board
An ignition control board has control over gas flow, the ignition timing as well as other safety devices. The ignition control board was always an important device that has now become a piece of the main circuit board instead of a separate board.
Elements of a worsening major ignition board
- The on-signal from the thermostat does not show up at the main board
- The main ignition cycle does not kick in when it is supposed to
- Every other potential issue in the HVAC system is inspected and seems to be just fine
