Nordyne P6SD Thermistor
A very basic thermistor is a specific kind of resistor which has a resistance that fluctuates depending on the amount of, or lack thereof, heat. They inform the heating and cooling system when the temperature in increasing or decreasing. The furnace or AC interprets the temperature in certain areas to do its job as it should.
What happens when my all-important thermister is not working properly?
- The whole HVAC system could possibly not even begin depending on which is the thermistor that is the problematic one
- Main blower could fail to begin to ramp up
