International Comfort Products CHP436AKA1 Ignition Control Board
The ignition control board is a safety device that has control over the natural gas, the ignition ignitor and a few other devices. It is an important device that is now usually a standard part of the main board instead of its own individual board.
Subtle cues of an ineffective ignition control board
- Communication from the thermostat never makes it to the control board
- Initial sequence fails to launch when called upon
- Any other device throughout the system is inspected and turns out to be flawless
