Carrier 38TRA060 Ignition Control Board
The purpose of the ignition control board is that it manages the main gas intake valve, the ignition timing and the flame sensing circuits. It is an important safety device that is now usually a piece of the main circuit board for safety reasons.
Some clues the major ignition board is dying
- Every other problem in the heating and cooling system is looked at and turns out to be good
- Ignition sequence declines to launch then the thermostat send a signal
- The initial signal from the remote thermostat never does reach the Carrier control board
