Goodman GHS80704BN Thermistor
A very basic thermistor is a type of resistor whose rated resistance is altered by temperature. The heating system needs to know the temperature in some specific areas of the system to know what to do next. They can tell the circuit board when a temperature reaches a certain point.
Key signs of a deteriorating temp regulating thermister
- The AC and heat system could possibly not operate due to a thermistor that is stuck open
- The blower could possibly fail to begin to engage full speed
