International Comfort Products H8MPN125J20A1 Ignition Control Board
The purpose of the ignition control board is that it oversees the main gas intake valve, the ignition ignitor and the flame sensing circuits. It has been a very important device that some companies have moved to be a major component of the main board for enhanced safety.
Indications the major ignition board will need to be replaced
- HVAC ignition system fails to start even when the thermostat kicks it on
- Initial communication from the primary thermostat does not show up at the main board
- Every other problem in the HVAC system is researched and comes to be in good health
