International Comfort Products NTN3050FBA1 Thermistor
In an HVAC system, a thermistor is a type of resistor which has a resistance that varies depending on the amount of, or lack thereof, heat. They can tell the main board when a certain temperature in increasing or decreasing. The heating and cooling system needs to know the temperature in some specific areas of the system to ensure that things are as they should be.

- The whole system could possibly never start due to any one thermistor that is damaged
- Blower fan could fail in its attempt to ramp up to full speed
