Carrier 48XL-A Ignition Control Board
Another safety feature is the ignition control board, which has control over gas flow, the ignition ignitor and the flame sensing circuits. It has been a very important device that some companies have moved to be a part of the main control board in order to have better control over the system.
How do you know if your ignition control board is failing?
- Ignition sequence refuses to initiate even though it is supposed to
- Any other problem in the HVAC system is researched and comes to be fine
- Communication from the home thermostat never gets to the main control board
