Samsung AVMWH052CA0 Thermistor
In an HVAC system, a thermistor is a type of resistor which has a resistance that depends on the amount of, or lack thereof, heat. They can tell the main board when a temperature reaches a certain point. The furnace or AC must know the temp in some specific areas of the system to be sure everything is going well.
Subtle cues of a faulty Samsung thermister
- The main blower could fail to begin to begin full speed blowing
- The whole system could possibly not even begin because of any thermistor that has failed
