Carrier FX4BNB060000AAAA Ignition Control Board
The main ignition control board controls gas flow, the ignition ignitor and other safety devices built into the system. It is an important electronic safety board that, in most cases, has become a piece of the main circuit board instead of having two separate boards.
Clues of an ineffective ignition control board
- Heating and cooling system refuses to launch when it is supposed to
- Signal from thermostat never moves to the main control board
- Every other problem in the system is researched and comes to be in good health
