I installed a new thermostat and the fan will not kick on when the heat kicks on. The wire in the wall has only white and black, and only the white is hooked up to the furnace. There is no green wire hooked up or coming from the furnace at all, so when the furnace kicks on, it ignites but the fan/blower will not kick on. I tried hooking the extra black wire that wasn't connected at either end to the green fan connections at each end, and still no luck. I checked the fuse on the furnace and that is fine also. The thermostat is a hunter model 44155C. No central AC so it's only the furnace ones that we're using. I hooked the white white to the W/B connection on the thermostat and have the jumper on the RH and RC ones. Any help would be appreciated.
