My 30+yr old Ruud furnace would not control the fan anymore. The control board looked like part of it overheated. Traced the part to a 62-24084-82 board. Found a video online with what looked like my exact furnace, and they were replacing the control board with this board and adding a separate flame sensor and said this board required it. I also ordered the 62-24044-71 flame sensor kit, and it included the mounting bracket and wiring and fit directing into my furnace without any adjustments or mod's. The board and sensor combo works perfectly, and I now have an additional safety sensor. NorthAmericaHVAC gave great service and fast shipping, I couldn't be happier!
