Carrier 38YKC036 Ignition Control Board
The main reason to have an ignition control board is that it has control over the gas valve, the ignition ignitor and some more sensing equipment. The ignition control board was always an important board that has now become a part of the main control board instead of having two separate boards.
Signals your ignition control board has little life left
- Any other device in the heating and cooling system is inspected and seems to be OK
- Ignition sequence does not fire up even though it is supposed to
- The initial signal from the thermostat does not show up at the main control board
