Trane TTX048D100A0 Thermistor
In an HVAC system, a thermistor is a certain type of resistor which has a resistance that changes as it depends on thermal temperature. They inform the heating and cooling system when a certain temperature reaches a certain point. The system needs to know the temperature in certain areas to do its job as it should.
Some warnings the system thermister is dying
- The blower could never begin to begin to ramp up to full speed
- The heating and cooling system could possibly not even begin because of the damaged thermistor
