Carrier 38HDC036 Ignition Control Board
Another safety feature is the ignition control board, which keeps an eye on gas flow, the ignition timing and all the flame sensing devices. It is an important safety feature that has now become a piece of the main circuit board instead of a separate board.
Key clues of a weakening main ignition board
- Initial ignition sequence is unwilling to fire up when it receives a proper signal
- The electrical signal from the thermostat never reaches the Carrier control board
- Any other potential problem in the heating and cooling system is inspected and turns out to be okay
