Direct fit and replacement for the original board that failed. Easy to install (make sure you mark and label your wires) and functions perfectly. We now have our Central Air back up and running. Tested all functions as well and no issues (Heat/AC/Fan).

This appears well made, it was well packaged with a static bag, instruction/schematic and it worked. Im very happy. My furnace has been working for a few days now and I am ordering a 2nd one to keep in the cupboard just in case.
