Carrier 50XT-A48 Thermistor
A very basic thermistor is a special kind of new age resistor that has a fluctuating resistance that changes as it depends on heat. The system control board needs to know the temperature throughout the whole system to know what to do next. They notify the system control board when a certain temperature has been reached.
Warnings to watch for in a failing thermister
- Main blower could never begin to begin to engage full speed spinning
- The heating and cooling system could possibly not operate because of the thermistor that is the problematic one
