Bryant 333BAV Ignition Control Board
The main reason to have an ignition control board is that it checks the main gas intake valve, the ignition ignitor and a few other devices. It has been a very important electronic circuit board that is usually a vital part of the main control board for safety reasons.
What to see if the ignition board is about to go out?
- Ignition system does not initiate even when the thermostat kicks it on
- Every other device in the system is inspected and turns out to be acceptable
- Signal from primary thermostat never makes contact with the control board
