Carrier 38TXA024 Ignition Control Board
The ignition control board is a safety device that controls the main gas intake valve, the ignition sequence and a few other devices. The ignition control board was always an important circuit board that has now become a piece of the main circuit board for safety reasons.
Major indications of a laboring major ignition board
- The primary ignition sequence will not fire up even when called upon
- Initial communication from the primary thermostat never makes contact with the main control board
- Every other device throughout the system is looked at and turns out to be acceptable
