International Comfort Products CAC442AKA1 Ignition Control Board
The main reason to have an ignition control board is that it keeps an eye on the main gas intake valve, the ignition ignitor and a few other devices. The ignition control board was always an important board that some manufacturers have decided to blend to be a piece of the main circuit board instead of its own individual board.
Major indications your ignition control board has very little life left
- The on-signal from the thermostat never reaches the main board
- HVAC ignition cycle is unable to launch then the thermostat send a signal
- Any other problem within the system is researched and comes to be acceptable
