Try this: unsnap the front portion of the thermostat from the wall and you will see some wires behind it. Turn the furnace power off. Now take the red wire (R) loose from the terminal and the white wire (W) loose and twist the ends together. Turn power back on. Let me know if furnace works and heats the house.
I am not trying to heat my house, I am trying to cool it. Does this apply to the air conditioning as well. Also, are you referring to the individual Thermostats in our house (like in the master bedroom), I don't see any wires. Maybe you mean in the basement?
I just need more help since this is not my expertise. I looked in the Thermostat and I see red, yellow and green wires plugged into separate outlets or areas in the box. Are you telling me to unplug each wire, wrap them all together and then plug them into one outlet?
