International Comfort Products NDN3100GFA1 Thermistor
A thermistor is a certain type of resistor which has a resistance that depends on the amount of, or lack thereof, heat. The heating and cooling system must know the temp in several different areas to make a decision on what needs to be done. They inform the HVAC system when the temperature in increasing or decreasing.
What signals that my thermister really needs to be replaced?
- Main blower may refuse in its attempt to begin full speed blowing
- No component may not function depending on which is the thermistor that is malfunctioning
