Carrier 38YCS042 Thermistor

In an HVAC system, a thermistor is a certain type of resistor that has a varied resistance that fluctuates depending on the amount of, or lack thereof, heat. They notify the HVAC system when a certain temperature has been reached. The heating and cooling system reads the temperature in certain areas to do its job as it should.
