Carrier 24ACA442A0030010 Ignition Control Board
The ignition control board is a safety device that oversees the natural gas, the igniter and some more sensing equipment. It is an important circuit board that, in most cases, has become a standard part of the main board for the sake of being more efficient.
Indications the major ignition board should be replaced
- HVAC ignition system is unable to launch even though it is supposed to
- The initial signal from the thermostat does not get to the Carrier control board
- Every other problem in the heating and cooling system checks out OK
