Bryant 120 Ignition Control Board
An ignition control board controls the gas valve, the ignition timing and a few other devices. It is an important circuit board that, over the years, has merged to become a vital part of the main control board for enhanced safety.
What signals that my chief ignition control board is on its last leg?
- Every other potential issue connected to the system is inspected and turns out to be acceptable
- The primary ignition sequence is unwilling to launch then the thermostat send a signal
- The electrical signal from the home thermostat never reaches the main board
