Carrier FF1DNA018075AAAA Thermistor
In an HVAC system, a thermistor is a certain type of resistor whose rated resistance fluctuates depending on the current temperature. The control board takes the temperature in several different areas to understand what is going on. They can tell the main board when the temperature reaches a certain point.
