Nordyne MS3BC030KA Thermistor
In an HVAC system, a thermistor is a specific kind of resistor whose rated resistance is governed by the amount of, or lack thereof, heat. They tell the circuit board when the temperature in increasing or decreasing. The heating and cooling system must know the temp throughout the whole system to make a decision on what needs to be done.
