Carrier 38SYG060 Thermistor
In an HVAC system, a thermistor is a certain type of resistor that has a fluctuating resistance that is contingent on the heat. The control board reads the temperature in order to ensure that things are as they should be. They inform the HVAC system when a certain temperature has been reached.
Indications your all-important thermister has to be replaced
- Blower motor may fail to begin to begin full speed blowing
- The heating and cooling system may never start up due to a problematic thermistor
