Carrier 58MVB100F10120 Thermistor
A very basic thermistor is a thermal resistor, whose resistance varies depending on the amount of, or lack thereof, heat. They tell the circuit board when the temperature in increasing or decreasing. The HVAC system reads the temperature throughout the whole system to know what to do next.
Signs of a faulty system thermister
- The system blower could never begin in its attempt to ramp up the airflow
- The system could possibly never start due to a broken thermistor
