International Comfort Products EF08B1500A2 Ignition Control Board
The main reason to have an ignition control board is that it keeps an eye on gas intake, the ignition sequence and all the flame sensing devices. It has been a very important circuit board that has now become a standard part of the main board instead of having two separate boards.
Major warnings your main ignition board will soon need to be replaced
- Every other device throughout the system is inspected and turns out to be just fine
- Signal from thermostat does not make it to the main control board
- Ignition sequence will not fire up when it receives a proper signal
