Carrier 38HDC024 Ignition Control Board
The purpose of the ignition control board is that it checks the main gas intake valve, the ignition sequence and all the flame sensing devices. It has been a very important safety device that, over the years, has merged to become a standard part of the main board for the sake of being more efficient.
Major signs the ignition board has very little life left
- HVAC ignition system is unable to launch when it is supposed to
- The initial signal from the home thermostat does not get to the Carrier control board
- Every other potential issue within the heating and AC system checked out to be okay
