A thermostat is just a device that keeps the temperature of something constant. They are probably most commonly encountered as part of a central heating or air conditioning unit in your home or office. Thermostats can operate in a range of ways but more often than not they will use a combination of two metals. As temperature changes the electrical properties of these metals change (see Ohm's law). Because the two metals change at different rates they can be compared with each other to establish the temperature - different metal pairings are used for different temperature ranges. The temperature data is then sent through an electrical signal to a boiler or air conditioning unit which will heat or cool the room as required.
Thermostat turned all the way up,thermostat defective, thermostat wired incorrectly, heating unit wired incorrectly, fan or heat relay stuck closed are the things I would look at to start.
No. If your referring to the fan on switch on the thermostat. The answer is no only the indoor fan runs if the thermostat is properly wired.

Your thermostat or condenser is wired wrong on the control side. Usually there is a terminal inside your furnace that has the same connection colors (Y, W, R, G, C) as your thermostat. It should be connected color to color to the thermostat with the 2 wires from the condenser wired to Y and C.
A light controlled by a switch are necessarily wired in "series", meaning that the electricity must pass through all components if the circuit is to operate correctly, assuming you actually have a source of electricity wired in as well.
The main disadvantage of wired system is that they are very complex. The wiring increases the complexity of the systems.
Parallel with the cooling contacts
yes they can, i have one wired and three wireless and they work together perfectly
You most definately unpluged the sensor wire. It's a single red wired that plugs onto a sensor just passed the thermostat.
A Refrigerator is technically a series because if one wire goes out all of the others go out
check the thermostat that runs the fan.
Is the theremostat set to Fan On? If not, is your house getting to the set temperature? If it is there could be a problem with the thermostat or it is wired incorrectly.
