Carrier 58DLA15510020 Thermistor
A very basic thermistor is a specific kind of resistor that has a fluctuating resistance that is altered by temperature. They tell the HVAC system when the temperature in increasing or decreasing. The main control board reads the temperature in certain areas to make a decision on what needs to be done.
Signs the system thermister will eventually need to be replaced
- The AC and heat system may not even begin to function due to a thermistor that is damaged
- The system blower fails to begin to engage full speed spinning
