International Comfort Products TCA460AKA1 Ignition Control Board
The purpose of the ignition control board is that it has control over gas flow, the igniter and all the flame sensing devices. It has always been a vital device that is usually a standard part of the main board instead of its own individual board.
How do you know when your main ignition board needs replacing?
- Any other device in the HVAC system is looked at and turns out to be okay
- The electrical signal from the remote thermostat never does reach the main board
- The main ignition cycle can not begin when it receives a proper signal
