International Comfort Products NAC230AKA1 Thermistor
A very basic thermistor is a specific kind of resistor whose rated resistance will fluctuate depending on the amount of, or lack thereof, heat. The heating and cooling system needs to know the temperature in order to be sure everything is going well. They can tell the main board when the temperature reaches a certain point.
Simple indications of a faulty system thermister
- Blower motor could fail to begin to engage full speed
- The AC and heat system could never start up due to any one failed thermistor

If you are going to be buying or ordering, do your due diligence and cross-check the correct model and also make a visual inspection in order to be sure the correct thermistor is being ordered. If you are unsure about the correct way of installing the new thermistor by yourself then it is probably best to find a professional in your area to do the work for you.
