Goodman GKS90453BX Thermistor
In an HVAC system, a thermistor is a thermal resistor, which has a resistance that is governed by the amount of, or lack thereof, heat. They tell the system when the temperature reaches a certain point. The heating and cooling system takes the temperature in some specific areas of the system to understand what is going on.
Subtle hints the Goodman thermister will need to be replaced
- The main blower may fail in the attempt to engage full speed spinning
- The entire system may not initiate the starting sequence depending on which is the broken thermistor
