International Comfort Products GNL125N20C1 Thermistor
A thermistor is a certain type of resistor that has a fluctuating resistance that is solely dependent on thermal temperature. The system control board needs to know the temperature in a few critical areas to know what to do next. They tell the main board when a temperature has been reached.
Major signs the system thermister needs replacing ASAP
- The main fan refuses in its attempt to get up to full speed
- The whole HVAC system may never begin depending on which is the thermistor that has failed
