Carrier 24ABR324G0031010 Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor whose resistance is directly proportioned to the amount of, or lack thereof, heat. They notify the heating and cooling system when a certain temperature has been reached. The system control board must know the temp in several different areas to know what to do next.
