International Comfort Products TCA442AKA1 Ignition Control Board
The main reason to have an ignition control board is that it has control over gas intake, the ignition ignitor and the flame sensing circuits. It has always been a vital device that is now usually a vital part of the main control board instead of having two separate boards.
Important clues to watch for in a failing major ignition board
- Initial communication from the home thermostat does not turn up at the International Comfort Products control board
- Any other potential problem in the HVAC system is researched and comes to be in good health
- Heating and cooling system refuses to begin then the thermostat send a signal
