Carrier FF1DNE024011AAAA Thermistor
A very basic thermistor is a certain type of resistor whose rated resistance changes as it depends on heat. They inform the system when the temperature has been reached. The furnace or AC must know the temp in a few critical areas to understand what is going on.
Some clues the Carrier thermister should be replaced
- The heating and cooling system may not initiate the starting sequence due to a malfunctioning thermistor
- Primary blower may fail in its attempt to ramp up the airflow
