International Comfort Products TCH Thermistor
In an HVAC system, a thermistor is a specific kind of resistor whose resistance varies depending on the heat. The furnace or AC reads the temperature throughout the whole system to be sure everything is going well. They inform the system when the temperature has been reached.
How do you know if your thermister needs replacing?
- Blower fan could fail in its attempt to ramp up the airflow
- The heating and cooling system may not initiate the starting sequence depending on which is the malfunctioning thermistor
