I bought the part for half of what I saw it online and it worked for my 2006 Ruud Achiever/Rheem system. I did all the troubleshooting/diagnosis that a good YouTube channel told me to do. I opened the inside system after all precautions taken and smelled something burned after fixing the outside cap. The blower motor was always running and my utility bill notified me about it. My burned board has 1005-83-1722A on it but this board works fine. It had all the matching connectors, same names on the board and same amount. Only difference is my old board didn't have a 3A fuse but had a place for it to be installed, this new board does. A quick swap, repaired some connectors and fired it up. It instantly worked and it's 73 degrees right now in my house.
