International Comfort Products GDJ100M16C1 Ignition Control Board
The main ignition control board has control over the gas valve, the igniter and a few other devices. It has always been a vital electronic circuit board that is now usually a vital part of the main control board instead of having two separate boards.
What happens when my International Comfort Products ignition control board is dying?
- HVAC ignition system refuses to launch at all
- Any other problem throughout the system is inspected and turns out to be in good health
- The initial signal from the primary thermostat does not make it to the main board
