Carrier 48XZ048130300 Ignition Control Board
The main reason to have an ignition control board is that it governs the main gas intake valve, the ignition ignitor and the flame sensing circuits. It has been a very important safety feature that some companies have moved to be a part of the main control board for enhanced safety.
Hints your main ignition board needs replacing
- The electrical signal from the home thermostat does not reach the main control board
- The ignition cycle can not begin when called upon
- Every other potential issue attached to the system is inspected and seems to be fine
