Haier HC42D2VAR Thermistor
A thermistor is a certain type of resistor that has a varied resistance that fluctuates depending on the heat. The HVAC system takes the temperature in order to know what to do next. They can tell the main board when the temperature has been reached.
How do you know when your system thermister is about to go out?
- The heating and cooling system may not even start due to a stuck thermistor
- Main blower may fail in its attempt to ramp up the airflow
