Carrier PTV Thermistor
A very basic thermistor is a special kind of new age resistor which has a resistance that is solely dependent on temperature. The system takes the temperature in some specific areas of the system to understand what is going on. They tell the circuit board when a temperature reaches a certain point.
Subtle hints your all-important thermister is failing
- The whole HVAC system may never start up because of any thermistor that is stuck open
- The blower may fail in its attempt to engage full speed
