Getting a 25 code. Board was replaced and model plug was not installed at startup. How can this be reset

1 comments:

Mr. Anderson

To reset the 25 code on a Bryant 315AAV furnace after replacing the board and not installing the model plug at startup, install the correct model plug into the control board. The furnace requires the model plug to identify the unit configuration. Once the correct model plug is installed, the error should clear, and the system can resume normal operation.
