Carrier 38E Thermistor
A thermistor is a type of resistor whose rated resistance is governed by current temperature. They tell the system when a certain temperature has been reached. The system control board needs to know the temperature throughout the whole system to do its job as it should.
Cues of a poorly working system thermister
- The AC and heat system may not even start due to any one inaccurate thermistor
- Primary blower could possibly fail in the attempt to begin full speed blowing
