Carrier 48JZ024040300 Thermistor
In an HVAC system, a thermistor is a certain type of resistor that has a varied resistance that is solely dependent on temperature at its location. The heating and cooling system interprets the temperature in a few critical areas to be sure everything is going well. They tell the main board when a certain temperature reaches a certain point.
