The power may come from the front roof AC. Access the filter of the roof AC and you will see a control board housing with wires. Usually, they run 12 volts TO THE ROOF AC board. They then transfer the power via the wall tstat wires to the wall tstat to power the wall tstat. BUT, there is still a separate 12 volt supply direct to the furnace. Have you checked the 4 wires the furnace? There will be a 12 volt RED positive and a Black 12 volt negative (ground). The other 2 wires (may be blue) are the 2 wires to the wall tstat. ONE of those blue wires will have 12 volt positive. IF you have 12 volt power to the furnace. Doug
