Carrier 38YRA030 Ignition Control Board
The purpose of the ignition control board is that it oversees the gas valve, the igniter and a few other devices. It is an important safety feature that is now usually a standard part of the main board in order to have better control over the system.
How do you know when your major ignition board is almost going bad?
- Every other problem within the system is inspected and seems to be just fine
- Initial ignition sequence is unable to fire up even though it is supposed to
- The electrical signal from the primary thermostat never turns up at the Carrier control board
