Carrier 38TDB060 Ignition Control Board
Another safety feature is the ignition control board, which manages the main gas intake valve, the ignition sequence and all the flame sensing devices. The ignition control board was always an important circuit board that has now become a piece of the main circuit board instead of having two separate boards.
Indications of a dying Carrier ignition control board
- Initial sequence is unable to kick in even when the thermostat kicks it on
- Communication from the main thermostat never moves to the main control board
- Every other problem within the furnace is looked at and turns out to be in fine condition
