Carrier RVC Ignition Control Board
The main reason to have an ignition control board is that it keeps an eye on the natural gas, the ignition timing and a few other devices. It has been a very important safety device that, in most cases, has become a part of the main control board for enhanced safety.
Major clues of a poorly performing major ignition board
- Every other thing in the system checks out OK
- Initial sequence fails to activate even when the thermostat kicks it on
- The initial signal from the main thermostat never makes it to the main board
