Goodman VSX130241 Thermistor
A very basic thermistor is a type of resistor that has a fluctuating resistance that will fluctuate depending on the thermal temperature. The furnace or AC must know the temp in a few critical areas to know what to do next. They can tell the main board when the temperature has been reached.
Indications of a poorly working system thermister
- The initial sequence may not even begin to function because of the inaccurate thermistor
- The system blower fails to begin to ramp up
