Carrier FF1DNE024000AAAA Thermistor
A thermistor is a type of resistor whose resistance will fluctuate depending on the amount of, or lack thereof, heat. The control board interprets the temperature in certain areas to make a decision on what needs to be done. They notify the system when a temperature has been reached.
Key signs of a declining Carrier thermister
- The system may not function due to a thermistor that is stuck open
- The system blower may fail to begin to ramp up the airflow
