International Comfort Products C9MPD075F12C2 Thermistor
In an HVAC system, a thermistor is a certain type of resistor whose resistance changes as it depends on temperature at its location. They tell the heating and cooling system when a temperature in increasing or decreasing. The HVAC system deciphers the temp in order to make a decision on what needs to be done.
