International Comfort Products PHAD42N1K2 Thermistor
A very basic thermistor is a special kind of new age resistor that has a varied resistance that is dependent on the amount of, or lack thereof, heat. They can tell the circuit board when a certain temperature reaches a certain point. The system interprets the temperature in some specific areas of the system to ensure that things are as they should be.
What warnings should I watch out for to know if my main thermister is almost dead?
- The blower could never begin to begin to ramp up the airflow
- The heating and cooling system could possibly not even begin due to any one stuck thermistor
