Goodman GCVC91155DXAA Thermistor
A very basic thermistor is a special kind of new age resistor that has a fluctuating resistance that is governed by temperature at its location. They tell the circuit board when a certain temperature has been reached. The heating system must know the temp in a few critical areas to know what to do next.
Hints of a failing Goodman thermister
- The system could never start up because of any damaged thermistor
- The system blower could fail in the attempt to engage full speed spinning
