Goodman GMS80905CN Thermistor
A very basic thermistor is a type of resistor that has a fluctuating resistance that depends on the temperature at its location. They can tell the main board when a temperature in increasing or decreasing. The furnace or AC deciphers the temp in several different areas to know what to do next.
Main clues the Goodman thermister needs replacing ASAP
- The system could possibly not operate due to a failed thermistor
- Blower fan fails in the attempt to ramp up the airflow
