Goodman ARPF37431 Thermistor
A thermistor is a thermal resistor, that has a fluctuating resistance that changes as it depends on the amount of, or lack thereof, heat. They inform the main board when the temperature reaches a certain point. The heating system deciphers the temp in several different areas to make a decision on what needs to be done.
