Goodman ATUF364216 Thermistor
A thermistor is a certain type of resistor which has a resistance that will fluctuate depending on the amount of, or lack thereof, heat. The heating and cooling system deciphers the temp in some specific areas of the system to know what to do next. They tell the heating and cooling system when the temperature in increasing or decreasing.
How do you know when your temp regulating thermister is failing?
- The entire system could possibly not even begin because of the thermistor that is stuck open
- The main fan could refuse in its attempt to get up to full speed
