Carrier 38AUZ Ignition Control Board
The purpose of the ignition control board is that it controls the main gas intake valve, the ignition timing and a few other devices. It has been a very important device that has now become a standard part of the main board instead of having two separate boards.
What are the indications that my Carrier ignition control board has a need to be replaced?
- Any other device connected to the system is explored and ends up being good
- Communication from the primary thermostat gets lost before it makes it to the control board
- HVAC ignition cycle is unable to kick in when called upon
