International Comfort Products PGAA36D1K6 Thermistor
In an HVAC system, a thermistor is a special kind of new age resistor that has a varied resistance that is solely dependent on heat. They tell the heating and cooling system when a temperature has been reached. The heating system must know the temp in several different areas to be sure everything is going well.
Signs the temp-regulating thermister needs replacing ASAP
- The AC and heat system could never start up due to any one problematic thermistor
- Primary blower could possibly fail in its attempt to ramp up the airflow
