International Comfort Products H9MPV125L20A1 Ignition Control Board
The purpose of the ignition control board is that it oversees the main gas intake valve, the igniter and some more sensing equipment. The ignition control board was always an important electronic circuit board that some companies have moved to be a part of the main control board for enhanced safety.
Signs your ignition control board is in dire straights
- Signal from thermostat never does reach the control board
- The main ignition cycle declines to initiate even when the thermostat kicks it on
- Any other problem in the system is looked at and turns out to be okay
