International Comfort Products TCA030AKA1 Ignition Control Board
The purpose of the ignition control board is that it manages gas intake, the ignition sequence as well as other safety devices. The ignition control board was always an important circuit board that, in most cases, has become a part of the main control board instead of a separate board.
General warnings to watch for in a failing ignition board
- The ignition system is unwilling to activate even when the thermostat kicks it on
- The electrical signal from the primary thermostat never reaches the main control board
- Every other potential issue in the system is explored and ends up being OK
