SPT WA-7500M Thermistor
In an HVAC system, a thermistor is a specific kind of resistor which has a resistance that changes as it depends on temperature. They notify the main board when a temperature has been reached. The main control board interprets the temperature in certain areas to make sure everything is running smoothly.
Do you know if your system thermister is not working right?
- The whole HVAC system could possibly not even begin due to any one failed thermistor
- Main blower could possibly fail in its attempt to ramp up the airflow
