International Comfort Products GDJ100M12C1 Ignition Control Board
The main reason to have an ignition control board is that it has control over gas flow, the igniter and some other sensors. The ignition control board was always an important board that is now usually a standard part of the main board for safety reasons.
Hints of a declining ignition board
- Initial communication from the home thermostat never reaches the International Comfort Products control board
- Every other potential issue in the heating and cooling system is researched and comes to be problem-free
- HVAC ignition system is unable to fire up even when the thermostat kicks it on
