International Comfort Products PGC048L120F Thermistor
A very basic thermistor is a special kind of new age resistor which has a resistance that changes as it depends on current temperature. They can tell the system control board when the temperature has been reached. The heating and cooling system reads the temperature in some specific areas of the system to ensure that things are as they should be.
Major signs of a faulty International Comfort Products thermister
- The entire system could never start up because of the thermistor that is stuck open
