Carrier 38HDL036 Thermistor
A very basic thermistor is a thermal resistor, which has a resistance that fluctuates depending on the amount of, or lack thereof, heat. The HVAC system reads the temperature throughout the whole system to be sure everything is going well. They convey to the main board when a certain temperature reaches a certain point.
Subtle hints the temp-regulating thermister needs to be replaced
- The main blower may fail in its attempt to engage full speed
- No component may never begin depending on which is the thermistor that has failed
