Carrier 48SX024-060 Thermistor
A thermistor is a certain type of resistor that has a varied resistance that is directly proportioned to current temperature. The system control board must know the temp in some specific areas of the system to do its job correctly. They can tell the circuit board when a certain temperature reaches a certain point.
What red flags are there that my Carrier thermister really needs to be replaced?
- The system may not even start depending on which is the stuck thermistor
- The system blower may fail in the attempt to engage full speed spinning
