Carrier 50QT Thermistor
A very basic thermistor is a type of resistor that has a fluctuating resistance that is governed by temperature at its location. The system takes the temperature in order to do its job correctly. They inform the circuit board when the temperature reaches a certain point.
Simple indications of a failing system thermister
- The system blower may fail in the attempt to engage full speed
- The initial sequence may not even begin to function because of the bad thermistor
