Carrier KLA Ignition Control Board
The purpose of the ignition control board is that it checks the main gas intake valve, the ignition ignitor and other safety devices built into the system. The ignition control board was always an important electronic safety board that, over the years, has merged to become a part of the main control board for the sake of being more efficient.
Important hints the major ignition board needs replacing ASAP
- The initial signal from the home thermostat never does reach the main control board
- Every other device within the heating and AC system is explored and ends up being a-OK
- The ignition cycle is unwilling to initiate no matter what
