The system control board needs to know the temperature in a few critical areas to know what to do next. They tell the system control board when a temperature in increasing or decreasing.
Warnings the temp-regulating thermister needs to be replaced
- The system may not operate due to any one thermistor that has failed
- The main blower could never begin in the attempt to begin full speed blowing
