International Comfort Products NDC7075BFA2 Thermistor
A thermistor is a thermal resistor, that has a fluctuating resistance that changes as it depends on temperature. The system control board reads the temperature throughout the whole system to make a decision on what needs to be done. They notify the heating and cooling system when the temperature has been reached.
