      Member Post posted an update

      October 22, 2025

      Has anyone had issues with a York YLAA machine and intermittent condenser fan problems? It’s a 454B machine and will run with BAS command for about 10 min and I’ll lose all fans on circuit 1. All fans are on an AYK580 drive. I can run in service mode and have no issues. It’s there a firmware update or any known issues with the I/O board that I should be looking in to? Thanks
