Carrier 48GX042060300 Ignition Control Board
The purpose of the ignition control board is that it governs gas intake, the ignition ignitor and some other sensors. It has always been a vital safety device that is now usually a vital part of the main control board in order to have better control over the system.
What to see if the Carrier ignition control board is dying?
- HVAC ignition cycle can not begin even though it is supposed to
- The on-signal from the remote thermostat does not reach the Carrier control board
- Every other problem in the heating and cooling system is inspected and seems to be all right
