Carrier 38TDB024 Ignition Control Board
The purpose of the ignition control board is that it checks out the main gas intake valve, the ignition sequence and all the flame sensing devices. It has been a very important circuit board that is now usually a major component of the main board in order to have better control over the system.
Cues of an ineffective ignition control board
- HVAC ignition cycle fails to kick in even when the thermostat kicks it on
- Any other problem in the system is researched and comes to be in good health
- Communication from the thermostat never makes contact with the main control board
