Carrier 38TKB048 Thermistor
A very basic thermistor is a thermal resistor, whose resistance depends on the temperature. The system control board reads the temperature in order to ensure that things are as they should be. They can tell the heating and cooling system when the temperature reaches a certain point.
Simple indications of a deteriorating thermister
- No component could never start up depending on which is the stuck thermistor
- Main blower could possibly fail in the attempt to get up to full speed
