We’ll begin with the Fault Code that is most misunderstood: 9 Red Flashes – Reversed Polarity. Current Furnace Control Boards require correct polarity of the Line Voltage and the Low (control) Voltage applied to it.Half of them seem to be correct and the other half is marked as "LIVE/NEU REVERSE" which is not that good, as far as I understand. One of those "LIVE/NEU REVERSE" sockets has a power strip plugged into it. It's a new power strip with ground connections and I've decided to check its sockets with the same device, just out of curiosity.I used a fluke circuit tester and determined that I did not have reverse polarity.
