How to Program an NFC Control Board

When replacing a control board equipped with Near Field Communication (NFC) capabilities, it’s critical to ensure that the new board is correctly programmed before attempting to operate the furnace. Each model is designed to operate with a specific Model Program Number, which defines the configuration and control logic for that unit. Programming the new control board with the correct program is essential for safe and proper furnace function.


Failure to program the board, or programming it with the wrong Model Program Number, can result in improper operation, system faults, or even damage to the furnace components. Always refer to the Model Program Number listed on the furnace rating plate, typically found on or near the burner compartment door. This number is unique to the furnace model and ensures compatibility between the control board and the rest of the system.


This article will walk you through the necessary steps to program a new NFC-enabled control board accurately using a simple step-by step guide.


The board can be programmed before it’s installed in the unit or after you have installed it. It is important to note that if you are choosing to program the board after installation, you must make sure that it is disconnected from power prior to beginning the programming process.


You will program the board using the Open Service APP. Below, you will find the QR codes for both the Carrier and Bryant versions. If you are on mobile, you may click the QR code to be taken to the app store. Once downloaded, you will be prompted to sing in. If you don’t have an HVAC Partners ID, you may continue as a guest.
