International Comfort Products HAC048AKA1 Thermistor
In an HVAC system, a thermistor is a type of resistor that has a fluctuating resistance that is dependent on the thermal temperature. They tell the HVAC system when a certain temperature has been reached. The system needs to know the temperature in some specific areas of the system to ensure that things are as they should be.
Major clues of a barely functioning thermister
- The AC and heat system may not even begin to function depending on which is the malfunctioning thermistor
- The main fan could possibly fail in its attempt to engage full speed
