Carrier 38TXA030 Thermistor
A very basic thermistor is a specific kind of resistor whose resistance changes as it depends on thermal temperature. They inform the heating and cooling system when the temperature reaches a certain point. The system needs to know the temperature in several different areas to know what to do next.
Major signs the system thermister is dead
- The whole HVAC system may not even start because of the thermistor that has failed
- The main blower could possibly fail in its attempt to ramp up to full speed
