Bryant 120 Control Board
The control board is designed to regulate everything including the gas valve, the ignition igniter, the flame sensor as well as the air circulator all at once. HVAC systems will not activate lest the main control board is properly connected to the unit. The chosen circuit board must have a matching part number consistent with both the brand and model of your Bryant 120 unit. You should always be careful when you are choosing a replacement board because of the diversity of models and types.
Key symptoms of a declining primary control board
- The system has to be powered down and back up a lot for it to run correctly
- There may be a fault code appearing somewhere on the circuit board
- Air conditioning or heating system cannot run properly
