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.
