Goodman ATUF193116 Thermistor
In an HVAC system, a thermistor is a thermal resistor, that has a varied resistance that changes as it depends on heat. They can tell the heating and cooling system when a certain temperature reaches a certain point. The system control board must know the temp throughout the whole system to know what to do next.
Important signs your all-important thermister has to be replaced
- The whole system could possibly not operate because of the thermistor that is malfunctioning
- The system blower may fail in the attempt to engage full speed
