SPT WA-1240H Thermistor
In an HVAC system, a thermistor is a thermal resistor, that has a varied resistance that will fluctuate depending on the amount of, or lack thereof, heat. They notify the HVAC system when a temperature has been reached. The control board reads the temperature throughout the whole system to be sure everything is going well.
Signs your all-important thermister will not last the year
- The blower could possibly fail in its attempt to engage full speed
- The AC and heat system may never begin because of any problematic thermistor
