Carrier 50XZ036300 Ignition Control Board
The purpose of the ignition control board is that it oversees gas intake, the ignition sequence and the flame sensing circuits. It has been a very important safety feature that some companies have moved to be a piece of the main circuit board instead of having two separate boards.
What happens when my chief ignition control board is dying?
- Every other device throughout the system is inspected and seems to be a-OK
- The ignition system is unwilling to initiate when called upon
- The electrical signal from the home thermostat never does reach the main control board
