Hi
Not sure if you pulled all the wires off the thermostat or if you just found some extra wires. I would like to start with the Thermostat. On your stat you have R, W, G, and Y terminal. From what I can see on your model the R terminal should go to the red wire on the furnace. The W terminal should go to the white wire on the furnace. The G terminal should go to the green wire on the furnace and the Y terminal should go to Condensing Unit contactor. So you should have a total of 4 wires hooked up at your stat.
Hope this helps, if the furnace still is not working after this we can move on to the next step.
