Carrier 30HH Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor that has a fluctuating resistance that is dependent on the temperature at its location. They can tell the circuit board when a certain temperature reaches a certain point. The system control board interprets the temperature in certain areas to understand what is going on.
Subtle cues of a defective all-important thermister
- The blower could never begin in its attempt to engage full speed
- The initial sequence may not operate because of the thermistor that has failed
