Carrier KFCEH1701C15 Ignition Control Board
The purpose of the ignition control board is that it oversees the gas valve, the ignition ignitor and other safety devices built into the system. It is an important device that is usually a piece of the main circuit board for enhanced safety.
Subtle cues to watch for in a bad major ignition board
- Initial communication from the main thermostat never gets to the Carrier control board
- Initial ignition sequence will not commence even when the thermostat kicks it on
- Any other potential problem within the system checks out just fine
