Carrier FV4CNF003 Thermistor

In an HVAC system, a thermistor is a certain type of resistor which has a resistance that is dependent on the thermal temperature. They inform the circuit board when a temperature has been reached. The heating and cooling system needs to know the temperature in order to ensure that things are as they should be.
