Carrier 38BRC042 Thermistor
In an HVAC system, a thermistor is a certain type of resistor whose resistance depends on the amount of, or lack thereof, heat. They can tell the HVAC system when the temperature reaches a certain point. The HVAC system needs to know the temperature in certain areas to be sure everything is going well.
Important hints the Carrier thermister will not last the year
- Main blower may refuse in the attempt to ramp up the airflow
- The initial sequence may not operate due to any one thermistor that is malfunctioning
