Samsung EH052CAV Thermistor
In an HVAC system, a thermistor is a specific kind of resistor that has a fluctuating resistance that will fluctuate depending on the temperature. The system control board must know the temp in some specific areas of the system to ensure that things are as they should be. They inform the circuit board when a temperature reaches a certain point.
Clues to watch for to know your thermister should be replaced
- The entire system may not function because of the bad thermistor
- Main blower refuses to begin to engage full speed
