Carrier 50JX-042 Thermistor
A very basic thermistor is a type of resistor whose resistance is altered by temperature at its location. The furnace or AC must know the temp throughout the whole system to ensure that things are as they should be. They notify the main board when the temperature in increasing or decreasing.
What warnings should I watch out for to know if my temp regulating thermister has to be replaced?
- The system blower could fail in the attempt to ramp up the airflow
- The AC and heat system may not even begin to function due to a improperly set thermistor
