Customer Reviews
With basic mechanical aptitude the board is simple to install. It was an exact replica of my OEM board so simple "plug & play" transfer of wires and a quick setting of dip switches (just match what your original board setting was) and I had this board installed inside of 5 minutes. It's still functioning flawlessly and the price was the best I could find anywhere. (even over $100 bucks cheaper than a national wholesaler that requires a HVAC license to purchase)
